In our research group we use state-of-the-art analytical techniques, involving mass spectrometry and spectroscopy, to study the fundamental physical chemistry of processes involved in global atmospheric change. Emphasis is placed upon understanding these chemical phenomena at a molecular level so that laboratory results can be reliably incorporated into environmental models. While research has focused in the past upon ozone depletion in the stratosphere, current projects all involve processes occurring in the lower atmosphere, with particular attention being given to the role that aerosol particles play in the chemistry of the troposphere, in global climate, and in urban air pollution. More details are given at our research group website.
