Overview


I study how cities are warming in a changing climate, and how we can design better tools to keep them livable. My research develops new statistical and machine learning methods to turn messy environmental data—such as satellite imagery, crowdsourced weather stations, and sensor networks—into reliable, neighborhood-level maps of heat exposure. By rigorously accounting for uncertainty and bias, I uncover patterns of vulnerability that would otherwise remain hidden. This work not only advances methods for analyzing complex environmental data, but also provides actionable insights for climate adaptation, from evaluating reflective surfaces and shading structures to guiding investments in urban greenery and cooling infrastructure. Ultimately, I aim to build the data-driven foundation for resilient, equitable, and climate-adaptive cities.

Refining Citizen Climate Science: Addressing Preferential Sampling for Improved Estimates of Urban Heat

Journal Article Environmental Science and Technology Letters · August 13, 2024 Studies of urban heat are often limited by their ability to measure air temperature; data are collected either at a few locations over time or at many locations at one point in time. Citizen science approaches to observing temperature provide a way to over ... Full text Cite
