Current Research

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.

We utilize a wide range of analytical chemistry techniques to study the chemistry of organic aerosols, including LC, GC, mass spectrometry, FTIR, NMR, and more.

In 2017 we conducted a six-week field campaign at the CU Art Museum, measuring indoor air quality inside one of the art galleries.
