I am an atmospheric chemist with broad interests in air quality and climate change. I am also Co-Director of the Repair Lab, an interdisciplinary environmental justice lab at UVA. My atmospheric chemistry research group in the Department of Environmental Sciences makes and uses measurements at the Earth’s surface, from aircraft, and space in polluted cities, agricultural areas, and forest canopies. Our focus is on reactive nitrogen, its role in chemical oxidation, its neighborhood-level variability, and emissions of the greenhouse gas nitrous oxide. We use observed spatial and temporal variability to derive mechanistic insight into processes taking place within cities and human-influenced environments. We work to find solutions to atmospheric problems that adversely affect human health and ecosystems.
