Ed Perfect

Earth and Planetary Sciences, UTK


Dr. Perfect is a Professor specializing in Vadose zone Hydrology. He joined the Department of Earth and Planetary Sciences at the University of Tennessee, Knoxville, USA in August 2001. As a member of the Department’s Hydrogeology Research Group he is actively involved in both research and teaching. His research interests are centered on relations between pore space geometry and soil/rock hydraulic and chemical transport properties, as well as understanding the scale-dependency of these relations. His research is, or has been, supported by the Petroleum Research Fund, National Science Foundation, U.S. Department of Energy, and U.S. Department of Defense. He teaches a variety of courses including a large introductory undergraduate course (The Earth’s Environment), an upper-level undergraduate course in Hydrogeology, graduate courses on Data Analysis and Fractal Modeling, and specialized seminars for upper-level graduate students.
