Dr. Chen got his degree from University of Washington in 2017. His focus of PhD study is change of extreme precipitation under future climate, and its implications on the safety of engineering infrastructures. At PNNL he is working on the climate projection of western US using regional climate models. At the same time, he will investigate how change of large-scale patterns affect local meteorological and surface hydrological processes.
