Charles Fitts

Charlie Fitts is in the Geosciences Department and he teaches several courses for DES majors, including GEY 100/101 Physical Geology, GEY 207 Atmospheric Science and Pollution, and GEY 420 Hydrogeology. He has been involved in the DES program since its beginnings in the early 1990s and served as DES's acting director from 2001 to 2003.

Charlie has a Ph.D. in Civil Engineering from the University of Minnesota and an M.S. in Geology from Cornell University. He worked in engineering consulting for 12 years before coming to USM in 1991. His research has focused on analytic solutions for mathematical modeling of groundwater flow and subsurface contaminant transport. He is the author of two groundwater modeling software packages: TWODAN for modeling groundwater flow, and SOLUTRANS for modeling solute transport.
