GeoHealth Lab investigates environmental health and health disparities through a geographic lens, with a particular focus on how human mobility across space and time shapes environmental exposure and health. We develop and apply GIS methods, geospatial data analytics, mobile and low-cost sensing, GPS and indoor positioning systems, machine learning, spatial statistics, and community-engaged research methods to better understand environmental exposures and their unequal impacts across populations. Our recent work extends exposure and health assessments across indoor and outdoor environments by focusing on indoor-outdoor spatial dynamics.

For prospective PhD students: Students interested in joining the GeoHealth Lab are encouraged to read the following paper before contacting Dr. Park, as it offers a helpful introduction to the lab's recent research on geographic context, environmental health, indoor environments, and human mobility.
