The aim of my research efforts is to further the understanding of the chemical and
physical properties of atmospheric secondary organic aerosols (SOAs). A large fraction
(80–90% in some locations) of atmospheric organic aerosol is secondary in origin.
The effects of SOA impact issues of climate change and human health, which in turn
have implications for weather, the hydrogeological cycle, and changes in ecosystem
stability. My program seeks to directly address important questions in SOA formation
mechanisms and chemical composition, and to relate chemical properties to the optical
properties of atmospheric aerosols.
