Assistant Professor

Basic Introduction:

Yan Liu is an assistant professor (associate researcher, doctoral supervisor, independent PI) at the School of Environment, Southern University of Science and Technology. He received his bachelor's degree and doctor's degree from Tsinghua University, and did postdoctoral research at Texas Tech University and University College London. His research interests are environmental hydrodynamics, with an emphasis on turbulent structures, sediment transport and benthic interactions in natural waters. He has published more than 10 papers on top journals, such as Water Resources Research and Journal of Fluid Mechanics, in many research fields. He serves as reviewers of Physics of Fluids, Journal of Hydraulic Engineering, International Journal of Sediment Research and so on.
