I am interested in improving the description of chemistry in regional and global models in order to advance our understanding and ability to predict air quality by more accurately simulating ozone and secondary organic aerosol. My research focuses on the development of reduced chemical mechanisms and their evaluation against field campaign observations and surface monitoring data.

  • Reduced chemical mechanism development
  • Tropospheric ozone formation and loss processes
  • Secondary organic aerosol formation
  • Model evaluation against aircraft and surface monitoring data

Current Topics

Reduced chemical mechanisms developed or in development:
  • MOZART-TS2 - Updates to isoprene and terpene chemistry (Schwantes et al., 2020)
  • MOZART-TS3 - Updates to alkane chemistry (In progress)
  • Mechanism updates to RACM for volatile organic compounds emitted from fires and volatile chemical products (In progress)
