Overview
I am interested in the spatial epidemiology of infectious diseases. My research utilizes geographic information systems (GIS) and geostatistical analyses to understand the spatial and spatiotemporal distribution of diseases, and their relationship with environmental and demographic factors. I currently have active studies evaluating the spatial distribution of numerous domestic and international infectious diseases, including SARS-CoV-2 (COVID-19), cytomegalovirus, influenza, and Lyme disease. Additionally I am interested in maternal-child health, and I have a number of ongoing studies of neighborhood health disparities in obstetrical care and birth outcomes. I am interested in GIS education and have conducted workshops on public health GIS in Mongolia and China.
