My research interests lie in the oxidation chemistry of VOCs, and its implications for air quality and climate change. My current research projects range from chamber studies to field campaign measurements. These projects use advanced mass spectrometric techniques (e.g. a chemical ionization mass spectrometer with filter inlet for gases and aerosols (FIGAERO-CIMS), and VOCUS PTR-TOF) and ancillary instrumentation for characterization of organic compounds in the gas and particle phase in different environments (e.g. arctic, high-altitude research stations). The aim is to identify the sources and to determine the detailed oxidation processes of organic compounds in these environments.
