Research Description

I work to develop and improve in-situ instrumentation to better study the sources and formation pathways of atmospheric particulate matter. By collecting and analyzing the specific organic compounds in particulate matter, we are able to track the co-variance of compounds in order to develop source profiles and therefore better understand where these pollutants come from. I focus on improving the time-resolution and extent of compounds measured, with the goal of studying compounds found in more aged air, which make up a significant fraction of all particulate matter. I intend to apply this knowledge to a study of the interaction between anthropogenic and biogenic emissions, which combine in atmosphere to increase particulate formation.
