About

I am an assistant professor in the Department of Environmental and Occupational Health at George Washington University. I completed my postdoctoral training at Yale University and my doctorate at Harvard University.

Our surroundings and environmental exposures affect our health. I research their health effects and investigate strategies to minimize detriments, especially among the most vulnerable. Lately, I focused on understanding if certain population groups are disproportionately exposed to or affected by air pollution, heat, and limited access to green spaces. To do this, I develop innovative methods to ascertain environmental exposure levels and estimate their consequent health effects.

I lead the Laboratory for Environmental Assessment and Population Health (LEAPH). Our work is supported by the NIH/NIEHS, Robert Wood Johnson Foundation, Research Nova Scotia, Social Sciences and Humanities Research Council, and Canada First Research Excellence Fund.
