I am currently researching the chemistry of the indoor environment through a combination of field work and laboratory studies. I am particularly interested in the indoor fate of semivolatile organic compounds and the relative contributions of deposition, ventilation, and chemistry to SVOC removal. Other projects focus on aerosol chemistry, reactions of multifunctional hydroperoxides, and gas-wall partitioning in Teflon environmental chambers and Teflon sampling lines.
