Research in the Hems Lab
The atmosphere is a chemically complex, dynamic, and multi-phase system. Through daily activities and actions as simple as breathing up to large-scale emissions, humans have a significant impact on the chemical composition of the atmosphere.
Our research focuses on the chemical reactions and fate of molecules in the atmosphere, both in indoor and outdoor environments. This research is motivated by the need to understand the impact of atmospheric chemistry on air quality and the climate. We will develop and apply analytical techniques, such as mass spectrometry, to identify and monitor atmospherically relevant chemical reactions. In particular, we are interested in understanding how emissions from common activities indoors, such as cooking, and reactions with atmospheric oxidants impact the chemical composition of indoor surfaces. We are also interested in investigating aqueous chemistry for the simulation of cloud water oxidation reactions.
