Michael’s current research efforts are focused on secondary organic aerosol (SOA) formation, SOA composition, and the contribution of individual SOA precursors to ambient particulate matter concentrations. These studies consist of laboratory experiments conducted in the NERL indoor smog chamber system as well as the collection of field samples. Detailed analyses of chamber-generated SOA samples produced from a variety of parent hydrocarbons (including monoterpenes, sesquiterpenes, aromatics, alkanes, PAHs, and isoprene) have been used to develop methods for estimating SOA contributions to ambient particulate matter, and to test and improve modeling tools used to support EPA regulations.
