My research interests are centered on studying the multiphase interaction of aerosol and trace gases within the atmosphere, using laboratory and field measurements.

My project at PSI is focused on the impact of transition metals, such as iron, on the chemical composition and physical properties of biogenically derived secondary organic aerosol (SOA). In particular, I am interested in how the presence of iron impacts the formation of SOA and its aging, and subsequently what impact this has on aerosol processing, climate, cloud formation, air quality and human health. To probe this chemistry, I study atmospheric proxy systems (e.g., monoterpene-derived SOA) using a combination of mass spectrometry based atmospheric simulation chamber experiments, and synchrotron-based single particle micro-spectroscopy measurements.

Aerosol Multiphase Photochemistry

Multiphase Photochemistry

The interplay between reactive oxygen species and the multiphase chemistry of nitrogen, halogen and secondary organic species in aerosol particles. Reactive oxygen species are at the origin of redox processes within the aqueous phase of aerosol particles containing secondary organic and inorganic species. The consequences are halogen and nitrogen oxides recycling, formation and loss of organics, which are all implicated in atmospheric oxidation capacity as well as the burden and health impact of aerosol particles.
