Chongxuan Liu is a chief scientist at US Department of Energy, Pacific Northwest National Laboratory. He received his Ph.D. degree in environmental engineering from Johns Hopkins University, Maryland, USA. His research areas are in geochemistry, biogeochemistry, and reactive transport of metals, radionuclides, and organic compounds in subsurface porous media. His expertise is in the development of mechanism-based models to mathematically describe geochemical and biogeochemical processes, reaction kinetics, and mass transfer through iterative experimental and theoretical investigations. He has published over 100 peer-reviewed articles with 2500 SCI-indexed citations. He is in the editorial board for several professinal journals. In 2011, he was elected as the Fellow of Geological Society of America for his contribution in geochemical and biogeochemical kinetics and diffusive mass transfer processes.
