Research Areas: GIS, Geospatial Data Analytics, Environmental Health, Air Pollution Exposure, Environmental Justice, Health Disparities, Health & Medical Geography, and Low-Cost Air Sensors
GeoHealth Lab seeks to understand environmental health (particularly exposure to air pollution), environmental justice, and health disparities using GIS, geospatial technologies, and spatial statistical methods.
The core concept within this broad range of topics is human mobility. Noting that people move around over space and time, GeoHealth lab goes beyond residence-based static approaches and utilizes fine-grained spatiotemporal methods and travel pattern data (e.g., GPS tracking data, travel-activity diaries, and data collected from low-cost sensors) to untangle the complexities of the social/environmental impacts on health and health disparities. Incorporating human mobility into environmental health research is important because it enables the examination of a full spectrum of geographic and temporal contexts in which people interact with environmental/social factors.
