I conduct interdisciplinary research on the environment. I have worked on diverse projects that cover: 1) atmospheric chemistry (modeling aerosols and tropospheric ozone); 2) environmental health (assessing the adverse health impacts of air pollution); 3) biogeochemistry (modeling global soil nitrous oxide emissions and quantifying soil GHG/ammonia fluxes); 4) climate science (estimating emissions of non-CO2 greenhouse gases), and 5) environmental policy/politics (analyzing the impacts of environmental standards and trade as well as analyzing policymaking processes).

My main research questions are related to the source and the magnitude of emissions linked to air pollution, ozone depletion and climate change, as well as the impacts of these emissions on humans and on society. I am also interested in what policy measures are available to reduce these emissions, and how politics play a role in policymaking process. My current projects are: 1) assessing the impact of agricultural practices on soil GHG/ammonia fluxes; 2) using low-cost air quality sensors to measure air quality; 3) creating a prototype of anaerobic digestion for reducing food waste on campus; 4) assessing the impact of plastic burning on human health and ambient air quality in Guatemala; 5) assessing the link between air quality exposure and asthma and 6) understand and mitigate the current and possible future soil heavy metal and metalloid and other chemical contaminant exposure among children in the Westside of Atlanta.

Our research is funded by the Emory Global Health Institute, the Emory SVPR AT THE INTERSECTION Fund, Emory Halle Institute, Environmental Protection Agency, the National Institutes of Health, and Syngenta.
