Adjunct Associate Professor of Environmental Chemistry and Exposure Assessment
My research examines critical questions about the public health consequences of air pollution through inter-disciplinary, biologically-relevant exposure assessment research. Specifically, my research combines traditional measurement methods with novel exposure assessment methods to advance how we think about air pollutant sources, exposures and health effects. In this effort, my research has four fundamental focuses, first to identify and apportion important air pollutant sources, second to show how individual behaviors modify air pollutant concentrations and through this their health impacts, third to use new exposure measures and approaches to examine source-specific impacts on biological pathways and to identify susceptible populations, and finally to develop GIS-based spatial smoothing methods to predict air pollutant concentrations for locations or for times when few air pollution measurements are available. Through these foci, my research has helped establish causality in pollutant exposure-health associations, offering physical explanations for the observed heterogeneity in particle-mediated health risks and for the differences in susceptibility among individuals. Scientific knowledge of this type is essential to identify the sources of ambient air pollution most important to public health.
