Volatile organic compounds (VOCs) are from a wide range of biogenic and anthropogenic sources. Their oxidation products play an important role in the formation of low-level ozone and secondary organic aerosol (SOA), thus having a big impact on air quality and Earth's radiative budget.
My research interests lie in the oxidation chemistry of VOCs, and their 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 the characterization of organic compounds in the gas and particle phase in different environments. The aim is to identify the sources and to determine the detailed oxidation processes of organic compounds in these environments.
