Closing the Circle — An Adjunct Engagement and a Proposed iSEE Lab at National Taiwan University

Dear Professor Chien, dear Crison,

Five years have passed since our last exchange, and I have thought of it often. In January 2020 you generously told me that National Taiwan University was ready to process my case, and you invited me to write a research proposal for the Ministry of Science and Technology. Together with Professor JP Chen, Dr. Tu Yi-Ching, Mr. Hsieh Yi-Huan, and later Dr. Hikaru Komatsu, we shaped the first seed of iSEE, Integrated Social, Economic and Environmental Indicators, under the theme Small Islands, Big Opportunities. Then the pandemic intervened, and destiny carried me to the United Nations Economic and Social Commission for Western Asia in Beirut.

That seed grew. Over five years I built and coordinated the Geo-Insights Laboratory, a working United Nations platform that now covers all twenty-two Arab states with more than one hundred geospatial data layers and sixteen published geo-stories, organized under seven Policy Lenses and one commitment, Leave No Location Behind. The idea we discussed in 2020 is no longer a proposal. It is a proven, operating system, recognized by the United Nations Office for Outer Space Affairs. What I could only describe to you then, I can now show you, layer by layer, story by story.

In these five years, our lines of thought have been running in parallel. You have been teaching geography to think in volumes rather than areas, from cloud water governance to the politics of geoengineering in the Anthropocene; over those same years I was building, in practice, a volumetric intelligence system, more than one hundred data layers stacked over one territory. You name your practice the field sciences, rather than model or laboratory sciences; that is precisely the practice I have carried across four continents and three decades, from a portable air sampler in a room, to a bicycle in the streets of a polluted city, to a satellite reading the whole Arab region. And when you write of wind-human resonance, I read it as a fellow cyclist, for the wind has never been a variable to me either, it is a companion. Two careers, two geographies, one way of thinking. We even share a Singapore chapter, you as a visiting research fellow at the East Asian Institute of the National University of Singapore, and I at its Energy Studies Institute in 2011.

Now the circle can close. I retire from the United Nations Economic and Social Commission for Western Asia on 3 October 2026, having earlier concluded my career at Statistics Canada, and I am returning home to Canada. This is the moment I have been waiting for. I would like to reignite our dialogue and finally build something constructive and innovative with you. My offer is simple and carries no burden. I can come to National Taiwan University as an Adjunct regardless of any funding. Once there, we can apply for funding together and establish an innovative iSEE Lab. I would prepare several small, focused proposals drawing on my architecture, engineering, urban planning, and Geographic Information Systems background, together with my Artificial Intelligence deep-applied interest, all pointed at one goal, the fusion of data into actionable policy insights, and each one mapped onto a theme you already lead.

Let me also answer, before you ask it, the question every department must ask. Funding is not my risk. Funding is my forte. Four times, in four institutions, on two continents, I have turned an idea into a funded, operating reality. At Public Works and Government Services Canada, in under one year, I secured funding for healthy building technologies through the eWAR (early Warning and Response) system I designed and implemented as a proof of concept, subsequently piloted by both McGill University and Concordia University. At Statistics Canada, I secured over three million dollars to run the largest environmental survey ever conducted on retail gasoline stations in Canada. At the United Nations Economic and Social Commission for Asia and the Pacific, I secured the funding to deliver capacity building on the System of Environmental Economic Accounting across island states. And at the United Nations Economic and Social Commission for Western Asia, in under one year, I secured full funding for the inception of the Geo-Statistical Laboratory, engaging more than twelve young local professionals to build the first and only full-fledged geospatial laboratory of its kind, known today as Geo-Insights, with more than one hundred data layers and a ready pipeline for user-centric, policy-making integration. So when I say I will arrive as an Adjunct at no cost, understand it as an opening position, not a ceiling. Attracting resources, and building young teams around them, is what I do.

On Artificial Intelligence, a word of humility. Since last year I have been fascinated by it and actively promoting its use in geo-statistical work, and I claim no formal background in it, because the field is new to all of us. What I bring is the judgment of a long practice, the ability to recognize when a model output violates physical or social reality, and the appetite to keep learning.

My calendar for the rest of 2026 is simple. I retire on 3 October. From 5 to 30 October I will be at the World Cycling Centre of the Union Cycliste Internationale in Aigle, Switzerland, training to become a bicycle mechanic, purely as a hobby, because at sixty-three I still ride everywhere and I have never stopped learning with my hands. In November I will be in Portugal at the Web Summit, promoting my startup NexaSEE Technologies. From late November I am fully free. I also deeply enjoy training and mentoring young people, and if you see a fit for me with your students, I am available.

All I ask for is one conversation. It would give me great joy to hear from you again.

Funded First One · Under One Year
Healthy Building Technologies, the eWAR (early Warning and Response) System
At Public Works and Government Services Canada, designed and implemented the eWAR (early Warning and Response) system as a proof of concept and secured its funding in under one year. The concept was subsequently piloted by both McGill University and Concordia University.
Funded First Two · Over Three Million Dollars
The Largest Environmental Survey of Its Kind
At Statistics Canada, secured over three million dollars to design and run the largest environmental survey ever conducted on retail gasoline stations in Canada, from street level to the national account.
Funded First Three · Across Island States
Capacity Building on Environmental Economic Accounting
At the United Nations Economic and Social Commission for Asia and the Pacific, secured the funding to deliver capacity building on the System of Environmental Economic Accounting across island states, the very geography of the original Small Islands, Big Opportunities idea.
Funded First Four · Under One Year, Fully Funded
From Zero to the Geo-Insights Laboratory
At the United Nations Economic and Social Commission for Western Asia, secured full funding for the inception of the Geo-Statistical Laboratory in under one year, engaged more than twelve young local professionals, and grew it into Geo-Insights, the first and only full-fledged geospatial laboratory of its kind, with more than one hundred data layers and a ready pipeline for user-centric, policy-making integration. The zero-cost arrival is the seed capital. The funded iSEE Lab is the harvest.
In line with Principal Component Analysis — which reduces many correlated variables to a more manageable number of dimensions to help explain most of the variance without discarding the information embedded in the correlations — the career I present to you and your team operates on the same logic. The apparent diversity of domains — building physics, urban planning, environmental epidemiology, geospatial intelligence, heritage conservation, environmental-economic accounting — is not disciplinary scatter. It is the variance structure of a single underlying research question: how do we make the hidden, visible?

Anchoring Work: Population-weighted ground-level ozone exposure integrates ambient air quality monitoring data with census population geography to produce a single national indicator that reflects not what concentration exists at a monitoring station, but what concentration the actual population — distributed across urban, suburban, and rural space — actually breathes. This methodology underpins the Canadian Environmental Sustainability Indicators framework and shifts the governance question from aggregate air quality to distributed exposure burden.

Anchoring Work: This Statistics Canada technical paper presents the Survey of Industrial Processes, a proof-of-concept methodology for collecting data on operational activities in retail gasoline outlets across Canada and modelling their gasoline vapour emissions. The approach integrates survey microdata with mathematical evaporation models to estimate volatile organic compound releases from small and medium-sized enterprises — a population systematically excluded from point-source inventories. The methodology bridges the street-scale emission source (the individual gasoline station) to the national air pollutant emissions inventory, demonstrating how disaggregated field data can be scaled to national environmental accounts. Soheil Rastan served as Unit Head of the survey team.

Research Theme 01
Volume Geography — Volumes Rather Than Areas
Territory understood vertically and volumetrically — from cloud water governance above the city to the layered atmosphere that people actually breathe within it.
Professor Chien's Focus: Teaching geography to think in volumes rather than areas · cloud water governance · vertical and volumetric territory · the politics of air and atmosphere
Scope: From the column of air above a city to the layered spaces in which environmental exposure, weather modification, and territorial claims actually occur
Connection: Every measurement instrument in this career has operated inside the volume, not on the map — a portable surface emission sampler reading a room, hourly fine particulate reconstruction reading the air column over Singapore, satellite change detection reading the whole Arab region layer by layer. The Geo-Insights Laboratory is, in practice, a volumetric intelligence system: more than one hundred data layers stacked over one territory.

Research Theme 02
Wind-Human Resonance and the Field Sciences
Geography practiced as a field science rather than a model or laboratory science — the atmosphere as lived, street-level experience, from Dalinpu, Kaohsiung, 2023.
Professor Chien's Focus: Field sciences rather than model or laboratory sciences · wind-human resonance · the lived experience of air, wind, and pollution at street level
Scope: How communities in industrial districts feel, read, and negotiate the atmosphere that surrounds them, and how that lived knowledge meets instrumented measurement
Connection: The face mask exposure study in Ho Chi Minh City measured exactly this — the air a person on a motorbike actually breathes, not the air a distant monitoring station records. A cyclist who has ridden two thirds of Taiwan knows the wind as a companion, not a variable. This career has always been field science first: real environments, real instruments, real people.
Anchoring Work: Velasco, Ha, Pham, Rastan 2022, street-level exposure · 2013 one-month cycling journey across Taiwan · in-situ sampling methodology across four continents
Research Theme 03
Critical Smart Eco Urbanism
The smartmentality of urban data politics — asking not only what smart city data shows, but who it serves, what it hides, and whether it is honest.
Professor Chien's Focus: Critical smart eco urbanism · the smartmentality of urban data politics · how data-driven governance reshapes cities and citizenship
Scope: From smart city dashboards to the governance structures behind them, and the gap between what indices report and what populations experience
Connection: The Singapore haze paper is a case study in honest data for smart cities: it showed that the published index and the actual fine particulate exposure had decoupled, a structural flaw in the reporting system, and it contributed directly to the 2014 reform introducing hourly public reporting. That is critical smart eco urbanism practiced from inside the data pipeline.

Research Theme 04
Global South, Small Islands, and the Anthropocene
International development, geoengineering in the Anthropocene, and the theme that started this whole dialogue in January 2020 — Small Islands, Big Opportunities.
Professor Chien's Focus: Global south and international development · geoengineering in the Anthropocene · climate governance beyond the developed world
Scope: From small island developing states to the twenty-two Arab states, the places where climate change arrives first and data arrives last
Connection: The 2020 proposal we shaped together — Integrated Social, Economic and Environmental Indicators for small islands, with shoreline density as the surrogate variable and university partners in the Maldives and Fiji — is ready to be revived, now backed by five years of regional advisory work in Mongolia, Vanuatu, Fiji, the Maldives, and Tajikistan, and a proven United Nations platform serving 473 million people.

Practice-grounded graduate teaching and youth mentoring hosted between the Department of Geography and the International Program of Climate Change and Sustainable Development — delivered by someone who has done the work, not just described it.
Home: Department of Geography · International Program of Climate Change and Sustainable Development · open to students of any home department
Approach: Field sciences first — every seminar anchored in a real instrument, a real dataset, or a real policy room, moving from the single object to the region through the Living Edge framework
Track Record: Graduate and professional teaching in Singapore (National University of Singapore, 2011), China (Xi'an University of Architecture and Technology, 2012), Vietnam (Ton Duc Thang University, 2013), and Canada, plus current instruction at the Institute for Higher Education (2025 — present, Sustainable Development and Environment)

Operational Stream 02
Research and Joint Funding
Arriving as an Adjunct regardless of funding, then applying jointly — several small, focused proposals to the National Science and Technology Council, each mapped onto a research theme Professor Chien already leads.
The Offer: The engagement begins with no financial burden on the host. Funding applications follow together, from inside the institution, where they are strongest
Funding Route: National Science and Technology Council of Taiwan — the successor of the Ministry of Science and Technology to which the original 2020 proposal was invited
Six Proposal Seeds: Volumetric geo-intelligence for a geography of volumes · Wind-human resonance, measured — street-level exposure instrumentation · Small Islands, Big Opportunities revived — the 2020 proposal, now backed by a working platform · Honest data for critical smart eco urbanism · Gridded economies for the global south · Heritage quarters and land cover change
Disciplinary Range: Architecture · Engineering · Urban Planning · Geographic Information Systems · applied Artificial Intelligence — all fused toward actionable policy insight

Operational Stream 03
Platform and Policy Translation
Direct transfer of the Geo-Insights Laboratory methods — more than one hundred data layers, sixteen geo-stories, seven Policy Lenses — into a National Taiwan University research asset that is co-built, open, and owned by its community.
What Transfers: The full data-to-policy pipeline of the Geo-Insights Laboratory — earth observation ingestion, geo-statistical fusion, Sustainable Development Goal monitoring, and the INSIGHT Universe analytical guide with its seven Policy Lenses
Openness: Code, data, and documentation openly available from the outset, so the research asset belongs to the university community, not to one person
Networks: A live international network across the United Nations Geospatial Network, national statistical offices, and regional advisory contacts in Asia and the Pacific — placed at the service of the iSEE Lab and its students
Policy Interface: Two decades of writing for deputy ministers and senior United Nations leadership — the honest broker practice of translating analysis into decisions without overstepping into advocacy

Air Quality — Singapore Haze 2013
PM2.5 reconstruction exceeding 600 µg/m³; NEA 2014 governance reform
The worst air pollution episode ever recorded in Singapore, reconstructed. Genetic algorithm solvers, Monte Carlo simulation, and stochastic statistical models were applied to impute true hourly concentrations from restricted data — revealing maximum likelihood 1-hour PM2.5 values exceeding 600 µg/m³, twice the reported 24-hour moving average. The decoupling between the PSI index and actual PM2.5 exposure was shown to be a structural flaw in the reporting system, not a measurement failure. The study contributed directly to NEA's 2014 reform introducing hourly PM2.5 public reporting.
Relevance to National Taiwan University: The Singapore haze paper was produced during my 2011 visiting fellowship at the National University of Singapore, the same institution where Professor Chien served as a visiting research fellow at the East Asian Institute. It is honest data for critical smart eco urbanism in action: the reconstruction showed the published index and the real fine particulate exposure had decoupled, and it contributed directly to the 2014 reform introducing hourly public reporting — the evidence-to-policy interface working from inside the data pipeline.

Metropolitan Ecosystem Sustainability Indicator
MODIS · road network · census microdata; 187 km² depletion over 11 years — Montreal
A validated multi-source spatial methodology for measuring landscape ecosystem depletion in metropolitan regions. Three independent data streams — MODIS satellite land cover, road network administrative records, and census population counts — are integrated into a 1-kilometre cell-level indicator system across the Census Metropolitan Area of Montreal, spanning 2001 to 2011. The methodology generates binary, ternary, likelihood, and intensity signals that can be mapped and aggregated into policy-relevant metropolitan sustainability dashboards.
Relevance to National Taiwan University: The Metropolitan Ecosystem paper builds the urban intelligence layer that critical smart eco urbanism needs as its evidence base — city-scale signals that show how urban environments actually perform and where intervention is most needed, at exactly the scale where Professor Chien's smartmentality critique operates.

National Agencies as Honest Brokers
Institutional design for science-policy navigation; Pielke framework applied
A conceptual and institutional analysis of how national statistical and environmental agencies navigate the boundary between scientific evidence production and policy advice — and what makes some institutions effective at this navigation while others collapse into advocacy or irrelevance. The concept of the honest broker, drawn from Roger Pielke Jr.'s framework, is applied to the specific institutional context of environmental-economic accounting agencies and ambient environmental quality governance systems.
Relevance to National Taiwan University: The Honest Broker paper addresses the governance of expertise in multi-stakeholder decision environments — how technical knowledge enters policy rooms without sliding into advocacy. It is the operating manual for the policy translation stream of the proposed iSEE Lab, and it speaks directly to a geography that practices field sciences inside real governance settings.

Geo-Insights StoryMaps — UN Development Portal
Policy-linked geospatial intelligence narratives; SDG monitoring; iSEE framework
A suite of policy-linked geospatial intelligence narratives published by the UN United Nations Economic and Social Commission for Western Asia Geo-Insights Laboratory across four series, covering gender, energy, water, land, and sustainability indicators across Arab UN Member States. The Arab Development Portal Geospatial Landing is the live platform through which these story-maps are delivered — a spatially-explicit, multilayered, time-series intelligence environment linking earth observation to Sustainable Development Goal monitoring at country and sub-national levels.
Relevance to National Taiwan University: This platform is the proof that the 2020 idea works. It demonstrates the full pipeline from earth observation and statistical systems to spatially explicit decision support, and it is directly transferable to the proposed iSEE Lab at National Taiwan University — methods, layers, geo-stories, and the seven Policy Lenses of the INSIGHT Universe.

Face Masks and Traffic Particles — Ho Chi Minh City
Personal exposure to ultrafine particles in dense urban street microenvironments
A field study measuring the protection afforded by different mask types against ultrafine and fine particles in the high-traffic street environment of Ho Chi Minh City — a dense urban microenvironment where traffic-generated particle exposure is among the highest in Southeast Asia. The study connects urban-scale air quality governance to individual-scale exposure, demonstrating the multi-scale logic that characterises the entire research profile.
Relevance to National Taiwan University: This is wind-human resonance, measured. The study captured the air a person on a motorbike actually breathes in a dense Asian city, not the air a distant station records — field science at street level, with the exposure equity framing that connects lived atmosphere to governance.

The Indoor Environmental Quality — Indoor VOC Measurement
Portable in-situ surface emission sampler; ASTM and FLEC validated; unexploited patent potential
The IEQ sampler is a portable, low-cost surface emission sampler capable of measuring volatile organic compound emissions from interior finishes and furnishings directly in occupied buildings, under real ambient conditions. Unlike the ASTM chamber and the Field and Laboratory Emission Cell, the IEQ sampler operates in situ. It demonstrated performance comparable to both reference methods while providing real-use field data needed to justify site-specific remedial action.
Relevance to National Taiwan University: Universities with heritage or legacy building stock present exactly the living laboratory in which this field instrument is most valuable. Adaptive re-use of older campus buildings involves existing fabric whose indoor emission behaviour is unknown until measured in place — the room-scale ground truth of a geography of volumes.

The Neighbourhood — Traditional to Contemporary
Communal habitation theory; urban morphology from medieval towns to contemporary metropolis
An examination of communal habitation across historical and contemporary urban scales, arguing that the deterioration of identity, liveability, and neighbourliness in modern residential environments is not inevitable but a consequence of losing the balance between public and private, dense and sparse, uniform and diverse. The analysis moves from medieval European towns to Ottoman cities to contemporary North American suburbs.
Relevance to National Taiwan University: Heritage and inclusivity as dimensions of urban liveability. This thesis provides the architectural and urban theory foundation for the heritage quarters and land cover change proposal seed — reading the built past not as amenity but as a constitutive condition of what a liveable city actually is.

Population-Weighted Ground-Level Ozone
Spatial exposure equity; census geography fused with air quality monitoring networks
A methodological contribution integrating census population geography with ambient air quality monitoring network data to produce population-weighted exposure indicators for urban regions — a technically precise approach to the spatial equity question in environmental epidemiology: not what concentration exists at a monitoring station, but what concentration the actual population actually breathes.
Relevance to National Taiwan University: Directly applicable to any dense urban environment where industrial land uses, major road corridors, and high-density residential blocks coexist — the exact spatial configuration of Dalinpu, Kaohsiung, where wind-human resonance was named. Population-weighted exposure reveals the equity dimensions that aggregate national indicators erase.

Heritage conservation is not a peripheral dimension of the urban research agenda. It is a diagnostic methodology for understanding how cities accumulate value over time — and what is systematically destroyed when urban development proceeds without accounting for that accumulation. Serving as Conservation Officer responsible for the restoration, conservation, preservation and adaptive re-use of twelve United Nations World Heritage Sites and Grounds in the Levant (1993–1997), this work was not antiquarian documentation. It was building pathology diagnosis: the identification of embedded structural vulnerabilities, hygrothermal failures, and material incompatibilities introduced by uninformed renovation interventions into historic fabric. That diagnostic capacity is the direct analogue of the indoor environmental quality measurement methodology — making visible the invisible costs of decisions made without understanding the physics of what they were modifying.

The connection to National Taiwan University is direct. A geography that reads territory in volumes, that practices field sciences, and that asks how cities remember themselves needs exactly this diagnostic capacity for the built past. Heritage quarters are where land-use change is most consequential and least reversible, and the proposal seed pairing heritage quarters with satellite land cover change detection stands on both the ground and the orbit: four years of hands-on conservation practice across twelve United Nations World Heritage Sites in the Levant (1993–1997), joined to the change detection methodology of the Geo-Insights Laboratory. The building pathology training — reading how historic structures respond to environmental stress, understanding material behaviour across centuries, assessing adaptive re-use potential — translates directly into the multi-layer spatial analysis that cultural geography and land governance research need to do convincingly. And four years of negotiating conservation decisions among governmental agencies, religious authorities, municipal governments, and international bodies in politically complex contexts gives me a practical understanding of the institutional and cultural constraints that field research on the built past must navigate.

Conservation Officer — Ottoman and Pre-Modern Urban Fabric
12 UN World Heritage Sites · Limestone pathology · Hygrothermal analysis · British Mandate and Ottoman planning layers
Role of Conservation Officer responsible for the restoration, conservation, preservation and adaptive re-use of 12 UN World Heritage Sites and Grounds.
Documentation engaged with the layered physical archaeology of cities whose urban form carries the successive inscriptions of Ottoman, pre-modern, and colonial planning regimes — a palimpsest of governance, identity, and spatial politics made legible through careful measured survey, photographic documentation, and archival cross-referencing of cadastral records, building permits, and oral history.
The work identified the structural vulnerability of vernacular limestone construction to the hygrothermal pathologies introduced by incompatible modern interventions: cement mortars over traditional lime-based fabric, tile overlays over hydraulic-lime floor systems, sealed facades over breathing wall assemblies. These are the embedded externalities of renovation decisions made without understanding the building physics of the material system being modified.
The diagnostic methodology I developed for reading historic structures — identifying original spatial logic, mapping deformation and intervention layers, assessing adaptive re-use potential — translates directly into the kind of multi-layer spatial analysis that cultural geography and land governance research need to do convincingly. A satellite change detection layer over a heritage quarter is only as authoritative as the conservation documentation beneath it.

Several of the 12 sites encompass UNESCO-designated urban quarters — among the most complete surviving examples of Crusader and Ottoman urban infrastructure in the world, overlaid by Ottoman reconstruction and inhabited by living contemporary communities whose spatial practices continue to adapt and transform the fabric daily. These are not museum cities. They are cities that have never stopped being cities, and whose World Heritage status creates a constant tension between conservation imperative and the right of communities to adapt their own living environment.
Documentation work engaged with vaulted halls and fortification systems, Ottoman khans and reconstructed souqs, and residential fabric where families have lived without interruption for centuries. The measured survey methodology combined traditional architectural drawing with photographic documentation and structural diagnosis of the specific failure modes endemic to these building stocks: salt crystallisation damage from marine microclimates, rising damp in deep masonry substructures, and long-term structural fatigue from sequential occupational changes across centuries of continuous inhabitation.
Heritage governance — deciding what is preserved, how it is interpreted, and who has authority over that interpretation — is a design problem as much as a policy problem. My experience navigating heritage governance across 12 sites in politically complex contexts gives me a practical understanding of the institutional and cultural constraints that field research on living heritage cities must navigate.
National Taiwan University Connection: Heritage quarters, community memory, and spatial identity — the cultural geography of the built past
Contribution 01
Data-to-Policy Intelligence at Scale
Twenty years of building systems that translate complex environmental and geospatial data into decision-support interfaces — the upstream layer that turns geography, climate, and sustainability research into decisions.
What this means for National Taiwan University: Policy intelligence begins before the dashboard. It begins when someone decides what data matters, how it is structured, and what it needs to communicate. My career has been spent on exactly that upstream problem — at Statistics Canada, at UN United Nations Economic and Social Commission for Asia and the Pacific, and now at UN United Nations Economic and Social Commission for Western Asia — building the data architectures that interactive systems depend on.
Specific Capacity: Environmental data visualization · geo-analytics dashboard design · decision-support interface architecture · multi-scale spatial data systems
Bridge to Professor Chien's Research: Your research examines how territory is governed, contested, and lived — in volumes, in fields, in the global south. I bring the complementary layer: how the data behind those questions is structured, validated, and made spatially coherent. Together, that is a complete pipeline from environmental reality to policy decision.
What I am bringing to National Taiwan University is something that no amount of institutional design can manufacture: the accumulated pattern recognition of someone who has spent over two decades working at the intersection of measurement, spatial analysis, policy advisory, and urban design — across disciplines that almost never speak to each other, and across geographies that force constant re-examination of what any framework actually assumes.
Contribution 02
International Teaching Across Asia-Pacific
Four prior international teaching assignments — Singapore, China, Vietnam, and ongoing — demonstrate the cross-cultural pedagogical range the International Program of Climate Change and Sustainable Development requires.
Teaching Record: National University of Singapore (2011 · Energy and Air Quality Nexus) · Xi'an University of Architecture and Technology, China (2012 · Environmental Sampling and Surveys) · Ton Duc Thang University, Vietnam (2013 · Environmental Sampling and Surveys) · Institute for Higher Education (2025–present · Sustainable Development and Environment)
Pedagogical Approach: Each assignment involved adapting technically rigorous content for culturally and linguistically diverse student cohorts — the same challenge the International Program of Climate Change and Sustainable Development faces every intake
What I Bring: Not just the capacity to teach internationally, but the demonstrated experience of having done so in three of the specific regional contexts — Singapore, China, Vietnam — from which your international student cohort is drawn
The 2011 National University of Singapore assignment was my first international teaching post, delivering a graduate seminar on Energy and Air Quality Nexus to a cohort drawn from across Southeast Asia. That experience — adapting environmental statistics to an interdisciplinary international audience — is precisely the bridge the International Program of Climate Change and Sustainable Development is built on. It is also a shared chapter: Professor Chien served as a visiting research fellow at the East Asian Institute of the same National University of Singapore where I held my fellowship at the Energy Studies Institute.
Contribution 03
Heritage Conservation as Field Science
Four years as Conservation Officer across twelve United Nations World Heritage Sites in the Levant provides the primary documentation of the built past that the heritage quarters and land cover change proposal seed is grounded in.
Heritage Record: Conservation Officer responsible for the restoration, conservation, preservation and adaptive re-use of twelve United Nations World Heritage Sites and Grounds in the Levant (1993–1997)
Relevance to National Taiwan University: Heritage quarters are where cultural geography, land-use change, and community memory intersect — a standing research theme in any geography department serious about the built past. The proposal seed pairing heritage quarters with satellite land cover change detection needs primary conservation knowledge of the kind that only comes from direct site practice. I am not a heritage commentator; I am a trained conservation officer with four years of hands-on work across twelve designated sites.
Design Bridge: The adaptive re-use methodology I applied across those sites — reading a historic structure's spatial logic and finding contemporary uses that preserve rather than destroy that logic — is a field-science methodology of the built environment — reading a historic structure's spatial logic and finding contemporary uses that preserve rather than destroy it
Universities researching urban transformation rarely hold in-house conservation practice, yet heritage fabric is where land-use change is most consequential and least reversible. My 1993–1997 work fills exactly that gap — pairing hands-on conservation grounding with the satellite change detection methods of the Geo-Insights Laboratory, so that the heritage quarters proposal seed stands on both the ground and the orbit.
Contribution 04
Multi-Scale Spatial Analytics for a Geography of Volumes
From indoor environmental quality to metropolitan ecosystems to regional geospatial systems — a career that has operated inside the volume at every scale, from a single room to twenty-two states.
Scale Range: Room (IEQ sampler research, Statistics Canada) → Building (healthy buildings, Public Works Canada) → Neighbourhood (urban morphology, M.Arch McGill) → City (metropolitan ecosystem paper) → Regional (UN United Nations Economic and Social Commission for Asia and the Pacific SEEA, five countries) → Global (UN Geospatial Network)
Match to Professor Chien's Framing: Volumes rather than areas is not a metaphor in this career — it is a literal description of the sequence of roles and research outputs across two decades, each one measuring what happens inside the volume, not on the map.
Smart Eco Urbanism Connection: Smart eco urbanism needs data systems honest enough to say whether the city is actually working. My geo-analytics and environmental statistics work provides exactly that feedback layer — closing the loop between governance intervention and measured environmental outcome
A geography department that thinks in volumes, practices field sciences, and looks toward the global south is the natural home for research that connects lived territory with the geospatial analytics that validates it. My Leave No Location Behind Initiative — which ensures no population is excluded from the data systems that govern their lives — carries that commitment into every scale the proposed iSEE Lab will touch.
Research Identity
Computational Geo-Intelligence Engineering
My research sits at the confluence of artificial intelligence-assisted geo-statistical analytics, environmental-economic accounting, and evidence-based sustainability governance — built over two decades of applied national and international practice.
Disciplinary Home: Computational Geo-Intelligence Engineering is the design and construction of geospatial artificial intelligence-assisted systems that fuse satellite imagery, sensor networks, administrative data, and alternative data sources into temporal, spatially-explicit intelligence platforms for governance and policy. It is where intelligent computing meets territory, and where cross-domain system integration produces measurable societal impact.

Methodological Core — Externality Computation: At the core sits what I call Externality Computation: the computational challenge of quantifying the hidden costs — water, energy, land, carbon, and human capital — embedded invisibly in economic activities and not included in the price signals that govern decisions. This transforms a local product or service from an economics observation into a computing problem: how does one architect a data pipeline that ingests multi-source socioeconomic and environmental signals — where pulsations and perturbations across demographic shifts, market pressures, climate variability, and land-use change are fused across spatial layers and temporal dimensions — and surfaces the invisible externalities that conventional indicators cannot see, cannot locate, and cannot price?

The iSEE Platform: That pipeline, engineered for the interlocking systems of society, economy, and environment in a given territory, is what I call the iSEE platform — Integrating Society, Economy and Environment. It is the research, development and demonstration project I bring to every institutional engagement.
Conceptual Framework
The Living Edge of Environmental Systems
Sustainability literacy is not an abstract attribute. It is the capacity to see what is actually in front of you and trace the invisible threads connecting it to everything else.
The Framework: I build sustainability literacy through what I call the Living Edge framework — beginning with the humblest, most familiar objects and revealing the staggering complexity of flows that connect them to environmental, economic, and social systems. Every living system has an edge: a boundary where the visible meets the invisible, where the priced meets the unpriced, where the local connects to the global.

The Computational Embodiment: The iSEE platform is the computational embodiment of the Living Edge framework — designed to operate from micro-scale to macro-scale, from the product on a shelf to the watershed that sustained it, from the household to the national account. It is not a model; it is a mirror for systems that cannot see themselves.

Why This Framing Matters: Most sustainability research begins with aggregate data and works downward. The Living Edge framework begins with a single tangible object and works outward — making the argument for environmental intelligence not through abstraction but through the irreducibly concrete. It is a pedagogical posture as much as a research methodology.
Entry Point
The Egg — Embedded Externalities and the iSEE Entry Point
A single ordinary product — rigorously examined — reveals the full depth of interlocking socioeconomic and environmental systems invisible to conventional indicators.
The Argument: Consider a single egg. Ask what it actually costs the system that produced it. It embeds water drawn from shared aquifers, land across field, barn, and feed grain supply chains, a chain of human capital spanning farmer, veterinarian, feed mill operator, grader, and logistics, and an energy cost running from hatchery to distribution. It embeds ecological services that are never invoiced: soil biology, watershed filtration, pollinator populations, coastal nutrient flows. None of these appear on the label. They are externalities — real costs paid by real systems, absent from the price signals that govern decisions. This is exactly what the iSEE framework is designed to make visible.

The Method: The method I bring to this inquiry — developed across twenty years of national and international environmental-economic accounting — is systematic externality mapping: identifying the water, energy, land, and human capital embedded in a product or service, quantifying the flows that conventional markets overlook, and revealing the governance gaps that allow those costs to be transferred invisibly onto ecosystems, communities, and future generations.

Why It Matters: That egg is not a simple commodity. It is a compressed archive of a territory's interlocking socioeconomic and environmental systems. And it is a compressed argument for why artificial intelligence-assisted geo-statistical intelligence matters — because only when we map all of these flows simultaneously, across space and time, does the full picture of sustainability and the leverage points for intervention become visible. This is where Computational Geo-Intelligence Engineering begins: not in the abstract, but in the hand.
Collaborative Philosophy
Fusion Without — Collaborate Within
The most powerful form of knowledge transfer happens not through lectures delivered to passive audiences but through doing together — shared research problems, co-built data platforms, and iterative consequence-bearing work.
The Conviction: My approach to visiting scholarship grows from a simple conviction: that the most urgent challenges of the artificial intelligence sustainability era do not respect the boundaries between academic disciplines, between theory and practice, or between visiting scholars and resident faculty. I came to collaborative engagement from decades of applied practice, and that reversal has shaped everything about how I work with others.

The Posture: I do not arrive with answers. I arrive with a project and an invitation to build it together and generate further innovative questions. My personal motto — "See no box, let alone think outside of it" — reflects my belief that the most sustainable solution is often the one we have not yet learned to see. Because the moment we name the box, we have already constrained the inquiry.

The Practice: In every seminar, guest lecture, or collaborative session I deliver, I bring real-world complexity: live Computational Geo-Intelligence Engineering data pipelines from active geospatial platforms, Externality Computation challenges from ongoing platform development, and the kind of institutional and methodological dilemmas that applied practitioners actually face. The question I always ask — What gets measured gets managed, but are we measuring the right things? — is not rhetorical. It is the research question that drives every module of the iSEE platform.
Collaborative Structure
Four Pillars of Engagement
Research and development · Faculty collaboration · Student engagement · International connectivity — the four integrated pillars of a visiting scholar residency built for consequential co-production, not passive knowledge transfer.
Pillar 1 — Research and Development: Building the iSEE platform's core modules — artificial intelligence-assisted geo-statistical analytics, environmental-economic accounting, and spatial equity intelligence — in active collaboration with faculty across relevant departments and colleges.

Pillar 2 — Faculty Collaboration: Working alongside researchers whose existing projects intersect with the iSEE platform themes; co-authoring publications; contributing to grant applications; and deepening cross-department connections that the iSEE platform is uniquely positioned to catalyse.

Pillar 3 — Student Engagement: Delivering seminars and guest lectures in relevant courses; advising graduate students whose research intersects with iSEE themes; and — where approved by course professors — inviting undergraduate and graduate students to contribute specific iSEE platform modules as structured course project components, creating a learning-by-building dynamic.

Pillar 4 — International Connectivity and Knowledge Exchange: Connecting the institution to international geospatial and sustainability intelligence communities; participating in research workshops and summits; and contributing to international recruitment and visibility goals. I arrive with active relationships across research institutions that I am ready to put directly in service of the institution's global connectivity ambitions — through joint publications, collaborative datasets, international exchange opportunities, and co-supervised graduate research.
Scholar as Catalyst
The Visiting Scholar as Research Catalyst
I bring the kind of knowledge not usually housed in any single institution — what it actually feels like to design a national environmental survey from scratch, to defend a geospatial sustainability indicator before sceptical government ministers, to watch a community's data tell a story that official monitoring has missed for years.
The Distinction: I use this experience not to lecture, but to open problems: to place a live challenge on the table and ask faculty colleagues and students to work through it with me. That is the essence of what I mean by "fusion without: to collaborate within" — and it is precisely how Computational Geo-Intelligence Engineering advances: not in isolation, but through the cross-domain collision of computing expertise and domain knowledge.

What Arrives: Two decades of applied geo-statistical and engineering practice do not dilute into a visiting scholar role — they distil. What arrives at the institution is not a professor who has read about building a development platform; it is the person who built one, who spent years negotiating data access with member states and governments, who stood before international expert committees to defend the methodology, who watched the platform reshape policy conversations in real time. That kind of knowing cannot be acquired through a literature review. It can only be transmitted — and only by someone who carries it.

The Scar as Pedagogy: When I collaborate with a student on a spatial equity analysis, I am not teaching from a textbook; I am teaching from a scar. That scar — the accumulated record of decisions made under uncertainty, of frameworks that failed and had to be rebuilt, of policy moments where data either changed or confirmed what was already feared — is a pedagogical asset available at the cost of an invitation.

Student Engagement
Student Engagement and Inclusion
An opt-in, project-based model — course professors approve student contributions to specific iSEE platform modules — academically credited through students' own courses and professionally acknowledged in platform outputs.
The Model: This is not a teaching load. It is an optional, project-based collaboration channel. Where faculty colleagues identify an opportunity, I am prepared to invite undergraduate and graduate students to contribute to specific iSEE platform components as structured elements within their own course projects — subject always to the approval and oversight of their course professors.

Examples of Student Contributions: A student in a geographic information systems course might contribute a land-cover analysis module. A student in environmental economics might build a natural capital valuation layer. A student in social science might design a spatial equity indicator. Each contribution would be academically credited through the student's own course, professionally acknowledged in the iSEE platform outputs, and co-supervised by the student's professor.

Design Principles: I design for diverse contributors — multiple modes of entry into the project, varied scope of participation, and full transparency about how each contribution fits the larger platform. No prior experience with geospatial platforms is required: the entry point is matched to what the student already knows how to do well.
National Taiwan University is where this idea was first invited. In January 2020 the door was open, the case was being processed, and the proposal had a name — Small Islands, Big Opportunities. The pandemic closed that door before I could walk through it. Six years later, I am not returning with the same proposal. I am returning with the proposal built, tested across twenty-two states, and recognized by the United Nations. The circle wants to close where it began.
S. Rastan — on closing the circle, August 2026

I am not responding to an advertised post and I am not seeking a permanent appointment. I am proposing to come as an Adjunct regardless of any funding, to apply for funding together once there, and to establish an innovative iSEE Lab — bringing the accumulated tools, datasets, methods, networks, and institutional experience of a two-decade career into the geography where the idea was born. All I ask for is one conversation.

Positionality
Positionality, Equity, and Open Collaboration
A multi-cultural engineer and scientist whose professional formation required daily negotiation of cultural difference — arriving not with a pre-packaged solution but with a project designed from the outset to be co-built, not imported.
Formation: I write this as someone who has spent a career working across significant cultural, linguistic, and socioeconomic difference — from environmental monitoring in Canada to refugee displacement mapping across Yemen, Somalia, Sudan, Iraq, Syria, and Lebanon, to community environmental surveys across Asia. My professional formation required daily negotiation of cultural difference, institutional complexity, and the limits of any single framework. My deepest conviction is that the best research happens when the people doing it genuinely respect what each other knows. The iSEE platform is designed from the outset to be co-built, not imported.

Equity and Disaggregation: My Leave No Location Behind work is grounded in the recognition that aggregate data hides the most vulnerable. Disaggregating by geography, gender, age, income, and disability reveals patterns of injustice that drive fundamentally different policy responses. I carry this lens into every research collaboration: I ask not only what the data shows on average, but whose experience is being erased by the average. The iSEE platform will be designed from the start to disaggregate — to make visible the environmental and social conditions of rural communities, Indigenous peoples, industrial workers, and lower-income urban populations as a core design requirement, not an afterthought.

Open Collaboration: I will hold regular open sessions with faculty and students about how the collaboration is working — treating that feedback as data to act on. I will mentor students from any background, regardless of home department or prior technical experience. I will make the iSEE platform's code, data, and documentation openly available from the outset, so the research asset belongs to the institution's community, not just to me.

Broader Commitment: I am committed to contributing to faculty equity initiatives, serving on inclusion committees, and bringing my international network to bear in creating exchange opportunities for students who might not otherwise access global artificial intelligence and sustainability research communities. Environmental sustainability and social justice are not parallel tracks — they are the same track.
The Strategic Case
Why a Practitioner-Scholar — The Strategic Case
Two decades of applied practice do not dilute into a visiting scholar role — they distil. What arrives is not a professor who has read about building a development platform; it is the person who built one.
The Paradox: There is a quiet paradox at the heart of contemporary research institutions. They invest enormously in training the next generation of researchers, yet the people most qualified to show those researchers what "applied" actually looks like — in live data pipelines, in government advisory rooms, in moments of institutional failure and unexpected insight — are rarely inside the building. They are busy with assignments elsewhere. The opportunity here is to bring one such practitioner inside deliberately — not as a visitor who delivers a lecture and leaves, but as a co-builder who stays, and builds something that stays and expands.

What Cannot Be Acquired Through Literature Review: I have managed large multi-stakeholder teams under deadline pressure in multiple languages across continents. I have written briefs that went to deputy ministers and reports presented to senior United Nations executive leadership. I have been the person in the room when artificial intelligence-assisted data analysis either confirmed what policymakers suspected or revealed what they had not dared consider. That kind of knowing cannot be transmitted through a reading list.

On Artificial Intelligence: The most common anxiety is that senior professionals will resist or be overwhelmed by artificial intelligence-driven transformation. My experience is the exact opposite. It is senior practitioners — those who have spent careers building mental models of complex systems, who can immediately recognise when a model's output violates physical or social reality, who have the judgment to know which questions are worth asking — who are best positioned to use artificial intelligence tools wisely and effectively. I actively build and deploy Computational Geo-Intelligence Engineering platforms in my current United Nations work. I can teach students not just to use these tools but to interrogate them — to understand what they amplify and what they distort — in ways that require exactly the depth of domain knowledge a long career provides.

The Invitation: Great research institutions have always understood that wisdom is not what you know — it is what you know how to do when things go wrong. That ambition deserves not only brilliant young scholars still finding their way, but also someone who has been asking the same questions long enough to know which ones are worth keeping — and who has chosen, at this point in a long career, to bring everything learned back into the room and build one more thing that matters.
