About


I'm an Earth scientist at the Pacific Northwest National Laboratory. My research interests include developing computationally robust models for global terrestrial biophysical processes that efficiently use high-performance computing. My research projects include:
  • E3SM: The U.S. DOE's Earth System Model in which my research focuses is on the development of biophysical processes in the E3SM Land Model (ELM) (code repository).
  • MPP-LSM library: Multi-Physics Problem (MPP) library is a standalone library that solves biophysics problems relevant to global land surface models (code repository).
  • TDycore library: A Terrestrial Dynamical Core for the ELM to solve 3D subsurface processes (code repository).
  • PFLOTRAN: A Massively Parallel Reactive Flow and Transport Model for describing Subsurface Processes (code repository).
  • Land Climate Process Team: Harnessing High-Resolution Terrestrial Information to Refine Atmosphere-to-Land interactions in Earth System Models
