In one sentence

I explore how AI and urban design can expand who can reason about, imagine, and shape urban transformation.

My story

Researcher by training.
Builder by instinct.

I work at the intersection of research, AI, design, and international program building.

Over seven years at MIT Senseable City Lab, my role has evolved from researcher to Research Scientist and Global Labs Lead, building research programs, teams, partnerships, and international initiatives across multiple cities.

I especially enjoy the phase when research is still taking shape: working alongside municipalities, local associations, and citizens, and creating the conditions for all of them to talk to one another. A city official, a community organizer, and a data scientist rarely describe the same street in the same way, and I like building the space where those perspectives meet and become a shared question.

I am most interested in what happens when research leaves the paper: when a new way of seeing the city becomes a tool, a collaboration, an experiment, or a decision.

A trajectory from studying cities to building the systems through which they can be studied.

I joined MIT Senseable City Lab in 2019 as a Visiting PhD Researcher. Since then, the scale of my work has progressively expanded, from individual research questions, to interdisciplinary projects, to building and leading international research programs.

Global Labs Lead
MIT Senseable City Lab

From one research program to an international research network.

Expanded this model across MIT Senseable City Lab's global programs, connecting research agendas with distinct urban contexts, institutional partnerships, interdisciplinary teams, resources, and long-term research strategies.

Research strategy

Research prioritization, cross-lab scientific direction, and development of new research opportunities.

People & teams

Leadership and coordination of 40+ researchers and students across an international network, including hiring, mentorship, resources, and team development.

Programs & resources

Coordination of multi-year, multi-million-dollar research programs, provisional budgets, and resource allocation.

Partnerships

Development of collaborations with governments, universities, industry, and local institutions.

Research infrastructure

Operating models connecting scientific ambition with partner priorities, data ecosystems, dissemination, and long-term program growth.

2024
Senior Postdoctoral Researcher
MIT Senseable City Lab

Consolidated an independent research agenda while expanding leadership across international research programs and interdisciplinary teams.

2026
Research Scientist
MIT Senseable City Lab

Research leadership connecting AI, urban systems, design, and implementation.

Today, I combine an independent research agenda with the leadership of interdisciplinary teams and international research programs, connecting computational urban research with design, planning, and real-world implementation.

Research + translation

Alongside program leadership, I maintain an active research practice spanning AI and cities, computer vision, public space, environmental exposure, mobility, and urban health, with work published in Nature Computational Science, Nature Water, Scientific Reports, and Computers, Environment and Urban Systems.

I also work beyond conventional academic outputs, translating research into tools, datasets, digital platforms, visualizations, exhibitions, installations, and public-facing experiences that connect scientific knowledge with planners, decision-makers, communities, and broader audiences.

For me, research does not end with understanding a city. It becomes meaningful when that understanding can inform how cities are planned, designed, and changed.

Global Programs

Cities as partners
in producing knowledge.

I build research programs with cities, not only about them, working with municipalities, universities, industry, and community organizations to turn shared urban challenges into evidence they can act on. Dubai, Rio de Janeiro, and Seoul each taught me a different way in, and how to keep very different partners working on the same question.

The common thread

Across these cities, the same research practice has emerged: start with a real urban problem, build what is needed to observe it, and translate that evidence into tools for planning and design.

Selected Projects

Research through questions.

Projects on how people experience cities, how cities shape health and everyday life, and how evidence can turn into design and planning decisions.

From human behavior and public space to AI, climate, and urban health, seven years of research forming an interconnected agenda around how cities can be observed, understood, and acted upon.

Urban Design

Streets, public space, campuses and neighborhoods, from studio teaching to built installations.

Environmental Planning

Heat, air quality, greenery and exposure, measured at the scale where people live.

Urban AI

Visual and reasoning AI as instruments to observe cities and support planning decisions.

Where this leads

From Urban Perception to Urban Reasoning and Collective Action

My research spans urban design and environmental planning. Images, sensors, and spatial models reveal patterns, but changing a place takes design judgment, local knowledge, and institutions able to act. I develop human-centered urban AI that connects evidence with spatial reasoning, design alternatives, and collective action.

  1. Urban evidence
  2. Spatial reasoning
  3. Design alternatives
  4. Collective action
Where it is going
  • Resilient and livable urban design: streets, shared spaces, and nature-based systems that improve everyday life and hold up under environmental pressure.
  • Reliable urban evidence and spatial reasoning: AI that observes and reasons with verifiable evidence and explicit uncertainty.
  • AI-mediated design and collective action: communities help define evidence, priorities, and alternatives before decisions are made.

The future I am interested in is not one in which AI designs cities for people, but one in which AI expands people’s capacity to design cities together.

How I teach

Teaching Cities as a Way of Seeing, Reasoning, and Designing

I teach urban design and environmental planning as spatial inquiry and collective transformation. Drawing, mapping, field observation, and critique are the foundation; data and AI expand the questions students can ask, without replacing design judgment or engagement with people.

  1. ObserveWalk, draw, and watch how places are used.
  2. InterpretCompare observation with spatial and environmental data.
  3. DesignBuild and test alternatives through critique.
  4. DeliberateExplain who benefits and what it takes to implement.

I want to educate designers who use new forms of intelligence without surrendering their own judgment.
