Our research is focused on understanding basic processes that impact air quality and climate. Broadly, we study how nitrogen moves through and between the atmosphere and biosphere, what the urban atmosphere can tell us about urban metabolism, formation of atmospheric aerosols as well as clouds, and how to build new techniques and improve existing ones for studying these important atmospheric processes.

The global nitrogen cycle

Urban metabolism

Studying the transport of nitrogen within the atmosphere and between the atmosphere and biosphere

Using chemical techniques to examine consumption of energy resources within urban environments

Aerosols and clouds


Exploring chemical formation of aerosol within the atmosphere and the kinetics of cloud formation

Designing and improving methods for answering important atmospheric research questions
