Prof. Lee specializes in hydrogeology, geostatistical and computational modeling, and geophysical application in shallow environments. His research focuses on developing numerical and theoretical methodologies that merge various hydrologic, geologic, and geophysical data into a stochastic modeling framework to characterize uncertain hydrologic processes, contaminant transport, and unknown subsurface structures. His recent projects are to quantify impacts of climate change and anthropogenic activities on groundwater through integration of surficial processes, land use and vegetation. He teaches hydrogeology, geotechnics, environmental geophysics, spatial data analysis, and introductory environmental science for both undergraduate and graduate levels.
