Environmental Chemistry

Motivated by the changing composition of the atmosphere, our research focuses on studies of atmospheric chemical processes, with attention given to the multiphase chemistry occurring on surfaces and with aerosol particles and clouds. A new research interest is the chemistry of the indoor environment.
