NARRATIVE
Current research focuses on the development and application of novel analytical methods to identify the products of in directed hydrocarbon + NOx irradiation experiments and to explore the formation of secondary organic aerosols in the troposphere through identification and quantification of condensed and gas phase reaction products. Primary duties include analyses and interpretation of multi-dimensional sample matrices through organic analytic determinations via GC-AED, GC-MS, MALDI-TOF-MS, HPLC, and aerosol particle sizing methodologies (Scanning Electrical Mobility Sizer, Condensation Nuclei Counter, VDMA, and conventional filter and impactor techniques).
Previous work focused on the development and application of novel methods to elucidate the influence of fuel modifications and advances in combustion technology on regulated and unregulated exhaust emissions and resulting toxicological responses. Additional previous work focused on the transport of persistent organic pollutants from the atmosphere to water bodies.
