Feng received his Ph.D. in Earth Sciences from the University of Southern California in 2021 and did his postdoc training at NCAR.

Feng's research interests fall in the application of paleoclimate modeling and data assimilation, model-data comparison, as well as machine learning, to better understand the climate system and validate climate models. In addition, Feng enjoys and has made lots of efforts on scientific software engineering, developing tools to facilitate efficient and reproducible research and open science.
