Changming He joined the Delaware Geological Survey in March of 2007. Dr. He's research interests include stochastic hydrogeology, geostatistical analysis, inverse calibration, colloids and colloid-facilitated solute transport in variably-saturated porous media, numerical modeling of groundwater flow and contaminant transport.
Dr. He has joined project teams working on application of numerical models to estimate ground-water availability in high-growth areas of the state and to assess impacts of wastewater disposal practices on ground and surface water resources.
