Broadly, I am concerned with environmental exposures and human health response, espeically in the context of socio-economic inequity. More specifically, I am interested in links between air pollution, mortality, and morbidity, and use of geographic information systems (GIS) and spatial statistics to inform exposure analysis and risk assessment. Thus far, my work and research has focused on ambient air pollution in urban areas. My current research evaluates use of modeling results from a sophisticated air quality model for estimating population and individual exposures. Modeling results represent a potential alternative and/or supplement to more traditional methods of exposure estimation that utilize data from ambient air quality monitors, which have limited spatial and temporal extents and resolutions. Future work will reply heavily on data of vital statistics, data from air pollutant and meteorological monitoring networks, demographic and Census data, and use of GIS and possibly satellite images.
