Our research focuses on understanding the changing composition of the atmosphere and its impacts on climate and air quality, with specific interest in ocean – atmosphere – cryosphere interactions and the atmospheric fate of marine trace gases.

We develop and apply analytical tools in both field and lab-based online mass spectrometry to better understand the evolving molecular composition of atmospheric aerosol and trace gases.
