NARRATIVE
My current research efforts are focused on secondary organic aerosol (SOA) formation, SOA composition, and the contribution of SOA to ambient particulate matter concentrations. These studies combine the use of indoor smog chamber experiments and the collection of field samples. Detailed analyses of chamber-generated SOA samples produced from a variety of parent hydrocarbons, including monoterpenes, sesquiterpenes, aromatics, and isoprene, have been used to develop methods for estimating SOA contributions in ambient particulate matter collected at several field sampling locations.
