Chen, Zilin and Doug attended the 2018 Chemistry of Indoor Environment Science meeting sponsored by the Alfred P. Sloan Foundation. The meeting took place at the University of Colorado Boulder on October 24-26. Chen presented her work on measurement of indoor organic acids and HONO during HOMEChem field campaign. Zilin presented his work on indoor multiphase ozonolysis. Doug (now at Bucknell University) discussed his research on indoor surface chemistry mostly done during his postdoctoral fellow at the Abbatt group. Prof. Jon Abbatt also gave a pre-meeting tutorial on surface chemistry with recent research progress at the Group.
