Analytical Chemistry

Interests and Expertise

My research encompasses the broad issues of atmospheric chemistry, composition and dynamics. My work is focused specifically on understanding the role the biosphere has in atmospheric chemistry, particularly how biogenic emissions affect the chemistry of ozone. This gas is in an EPA regulated pollutant that has been implicated in local and regional air quality. My investigations focus on making measurements in the field and then, computer modeling the resultant data in order to understand the complex sources, sinks and reactions of this important atmospheric gas.
