Research Interests: Heterogeneous and Photochemical Reactions Modeling Tropospheric Chemistry. Earth’s atmosphere contains large quantities of airborne particulate matter, such as mineral dust, which provide solid-air interfaces that can support heterogeneous chemistry with gaseous pollutants, such as NO2 and O3. We use infrared spectroscopy to study model systems involving surface adsorbed semi-volatile organic compounds (SVOC’s). Attenuated total reflectance IR (ATR-FTIR) and diffuse reflectance IR spectroscopy (DRIFTS) allow for direct identification of surface adsorbed products in these systems. Furthermore, by comparing the kinetics under dark and light conditions, we can assess the importance of photochemical pathways, while isotopic studies provide insight into reaction mechanisms.

Photochemistry of Early Photographic Processes. Niciophore Niepce developed the world’s first extant photograph circa 1824 using Bitumen of Judea as the light sensitive material. We are using ATR-FTIR spectroscopy to investigate the photo-oxidation and photo-crosslinking reactions of bitumen.
