Biography

Zexuan Xu is a Research Scientist at Earth and Environment Science Area, Lawrence Berkeley National Laboratory (LBNL). He joined Berkeley Lab in 2016 as a postdoctoral researcher, and held a joint appointment as Data Science Fellow at Berkeley Institute for Data Science during 2017-2019. Before joining Berkeley Lab, Zexuan received his PhD degree in computational hydrology modeling at Florida State University.

Zexuan Xu has interdisciplinary training in environmental science, climate science, data science, and software engineering. He is leading the Advanced Long-term Monitoring Systems project at Berkeley Lab to develop AI and physical-based high-performance modeling for ensuring environmental protection at DOE’s legacy sites. He is also developing tools and softwares for supporting climate resilience data processing and analysis to prepare for the impending effects of climate change. In addition, he is also working on watershed science, and developed computational integrated hydrology and reactive transport models through a community-driven software ecosystem.
