I am a PhD student at the Atmospheric Chemistry Modeling Group, Harvard University.

Research Focus

  • Development and evaluation of atmospheric chemistry models such as the GEOS-Chem chemical transport model (CTM).
  • Development of coupled meteorology/climate-chemistry models by coupling models such as WRF, CESM2 to the GEOS-Chem CTM.
  • Writing high-performance, scalable code to do science better
  • Always waiting for new adventures!

Current work

  • Development of the Harmonized Emissions Component (HEMCO) and interfacing it with the Community Atmosphere Model (CAM) in CESM2
  • Running the GEOS-Chem model and WRF-GC with HPC on the cloud.
  • Software maintenance of the WRF-GC coupled model.
