Curriculum Vitae


My research interests broadly focus on chemistry–climate interactions, with specific emphasis on extreme events such as air pollution episodes and heat waves. I use surface measurements of pollution (ozone and particulate matter) alongside chemistry–climate models (CCMs) to understand the meteorological and chemical controls on the formation and multi-day persistence of pollution episodes. I am especially interested in understanding how natural (e.g., biogenic emissions, dry deposition) and anthropogenic (e.g., increased energy demand) feedback processes that contribute to pollution episodes and how they can best be represented in CCMs.
