Research Interests

My research interests evolve around developing numerical (computer) models to better simulate and understand the weather and climate of our planet with a particular emphasis on clouds. Over the years, I have worked with models spanning a wide range of scales and applications; from relatively simple models that can run on a laptop computer to complex Earth System Models requiring High Performance Computing resources. Example of models include:

  • Single-column (1-D) model to simulate atmospheric boundary layer turbulence and clouds (later known as CLUBB).
  • Large eddy simulations (LES) models capable of resolving (3-D) boundary layer turbulence and clouds in a limited domain (e.g. RAMS and COAMPS).
  • Global atmosphere models (e.g. GFDL-AM3).
  • Fully coupled physical Earth System Models (e.g. E3SM).
