My primary research focuses on air quality science and policy, stratospheric ozone, and climate change. My team uses observations from satellites, balloons, aircraft and ground based instruments to test our understanding of atmospheric composition represented in photochemical models. This information is used by policy makers to ensure that the best available science informs the development of air quality regulations. We’re also investigating how carbon capture sequestration technology may also improve air quality. In recent years, I’ve had the opportunity to expand my collaborations to include epidemiologists studying the impact of air pollution exposure on fetal development and birth outcomes. I’ve also begun working with faculty in UMD’s Smith School of Business to investigate climate finance risk. This has led to the creation of a new executive education program and an MS in climate finance risk. Our work is funded through NASA, DOE, MDE, and NIH.
