Research framework

Healthy cities as a connected system

Our work follows a research chain: observe dynamic populations, understand movement, measure environmental encounters, identify inequality, sense health change and estimate health effects.

01PEOPLE

PEOPLE

Population Dynamics

Mapping where people are, how urban populations change through time, and why static census surfaces are not enough for fast-moving cities.

Questions

  • How can hourly population distributions be mapped at national scale?
  • How can models remain reliable across different places and times?
  • How should dynamic population surfaces inform planning and emergency response?
02PEOPLE

PEOPLE

Human Mobility

Understanding movement between and within cities, and how mobility reshapes exposure, accessibility, transmission and urban resilience.

Questions

  • How can fragmented mobility signals reveal population movement?
  • How does mobility connect cities during public-health emergencies?
  • How do daily activity spaces change the environments people encounter?
03ENVIRONMENT

ENVIRONMENT

Environmental Mapping & Exposure

Measuring changing encounters with air pollution, green and blue space, heat, floods, wildfire and the three-dimensional built environment.

Questions

  • What changes when exposure follows people rather than residential addresses?
  • How can satellite, sensor and volunteered data be integrated?
  • How can exposure uncertainty be made visible and useful?
04ENVIRONMENT

ENVIRONMENT

Environmental Inequality

Identifying who benefits from environmental amenities, who bears environmental burdens, and how disparities vary across cities and populations.

Questions

  • Which populations experience the largest environmental disadvantages?
  • Do inequalities change across spatial scales and urban–rural definitions?
  • Where could targeted urban interventions reduce unequal exposure?

HEALTH

Urban Health Sensing

Using digital traces, search behaviour and spatial signals to observe population health dynamics between conventional surveys and clinical records.

Questions

  • What can online behaviour reveal about rapidly changing mental health?
  • How can digital signals be validated against established health evidence?
  • Where are social sensing methods useful—and where are they biased?
06HEALTH

HEALTH

Health Effects & Burden

Linking environmental conditions to mortality, respiratory health, mental well-being and unequal disease burdens across population groups.

Questions

  • How do environmental hazards affect health across population groups?
  • How do multiple hazards and urban conditions interact?
  • How can epidemiological evidence support equitable urban action?
