My research over the years has focused on many aspects of atmospheric chemistry related to air quality and climate change, including the studies of the atmospheric oxidation mechanisms of anthropogenic and biogenic carbon‐containing species and halogen chemistry.

At present, my group’s research encompasses gas phase atmospheric chemistry, secondary organic aerosols formation, field studies and long-term atmospheric observations.
