Research Interests

My research interests include the development of methods for aerosol and air pollution measurement, understanding the generation, fate, and transport of semivolatile organic compounds in rural, urban, and industrial environments, and development of improved diagnostic techniques for assessing human exposures to and adverse health effects of air pollution. Current research projects include the development of a lung-dose aerosol sampler for in vitro health effects research, characterization of particulate matter emissions from internal combustion engines, and integration of global positioning satellite (GPS) tracking technology with real-time monitoring of human exposure to airborne particulate matter.
