Dr. Jiwen Fan has a wide range of research experience and interests, varying from atmospheric chemistry, aerosol formation, to cloud and climate studies. Jiwen has extensive experience in studying aerosol-cloud interactions with explicit cloud microphysics, especially for mixed-phase stratiform and deep convective clouds. Her current research projects include: (1) understanding ice formation mechanisms and mixed-phase cloud properties and improving ice nucleation and deep convection parameterizations, (2) exploring aerosol-cloud interactions on the process-level and improving aerosol-cloud interaction parameterizations in the regional and global models, and (3) developing scale-aware cumulus parameterizations and testing scare-aware turbulence parameterizations.
