Professional Profile

Research Scientist I at CIRES


My research mainly focuses on the land surface modeling, especially on the subgrid processes and snow processes. I have developed a stochastic subgrid snow model, the FPE snow model (https://doi.org/10.1029/2017WR022017), for representing subgrid variability of snow in land surface and hydrological models. I also developed a scale-aware parameterization for estimating subgrid variability of downward shortwave radiation (https://doi.org/10.1029/2019JD031563), which could be potentially used to estimate subgrid variability of the radiation-driven variables. I am also interested in hydrological modeling, land-atmosphere interactions, and stochastic modeling.
