Organic aerosol markers in atmospheric processes, biomass burning emissions
Biosketch

Currently, I have been working with a new, inexpensive, and robust method to measure smoke marker compounds, such as levoglucosan, using high-performance anion-exchange chromatography with pulsed amperometric detection (HPAEC-PAD). This approach offers numerous advantages over traditional methods, including extraction of the filter directly in water and the ability to directly analyze the filter extract for levoglucosan. One of the current applications of this method is on source samples collected at the Fire Science Laboratory in Missoula, MT. This work is being performed in order to generate much needed smoke source profiles that could be used to assess the contribution of wildfires and prescribed fires to the total organic carbon concentrations.

During my Ph.D. work at Georgia Tech I developed a method to measure water-soluble organic carbon (WSOC) aerosols in real-time both on the ground and when airborne. I also developed methods to chemically characterize WSOC using XAD-8 resin and size-exclusion chromatography. Both these techniques were then used to try to further understand the sources of WSOC.
