I'm an environmental epidemiologist, whose mission is to understand the relationship between human health and complex environmental exposures. I have a particular interest in evaluating how extreme weather (notably drought, heat, and precipitation), climate, and air pollution influence population-level health. I frequently use spatial analysis and Geographic Information Systems (GIS) to improve exposure assessment and better understand the role of environment with disease outcomes. Most of my research involves secondary analysis of large data sources (e.g. hospital records, Medicare), but more recent work has focused on collecting personal exposure data. My work emphasizes policy relevant findings that can inform decision making to better protect public health.
