Dr.Gu graduated with a Ph.D. from the University of Virginia in the United States with a major in Environmental Science. He completed a postdoctoral study at the University of California, Berkeley, and the Lawrence Berkeley National Laboratory. Dr. Gu held faculty position in Appalachian State University and Beijing Normal University prior to joining DKU. Key areas of his research include pollutant transport and fate at the land-atmosphere and land-water interfaces, groundwater-surface water interaction and its impacts on nutrient cycles, the multiphase flow and reactive transport model in porous media. Current research projects include soil organic amendment by solid wastes and its ecological risk assessment, greenhouse gas emission from human-disturbed lands, sponge city and stormwater management, bio-geomorphic effects on tidal channel evolution, etc.
