Much of my current research focuses on trying to better understand the chemistry and composition of ambient aerosols. To do this, I conduct measurements of and develop methods to analyze the composition of aerosols. This is done by collecting samples on the ground and airborne both in near real-time using techniques such as a Particle-into-Liquid Sampler (PILS) and off-line using filters. Many of the analysis techniques I employ on these samples involves liquid chromatography. Along with traditional anion and cation chromatography, I have developed methods for measuring carbohydrates using high-performance anion-exchange chromatography with pulsed amperometric detection (HPAEC-PAD) as well as organic acids and amines.
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.
