Greetings, and thanks for visiting my webpage! I am a physical geographer with many teaching and research interests, especially in water resources, groundwater monitoring and remediation, and environmental geology. Most of my studies involve interactions between humans and physical environments. I have been with the Department of Geography at UNT since 1992. Previously, I worked at environmental consulting firms specializing in soil and water pollution. My educational background includes a B.S. and M.S. in Geology from Allegheny College and Wright State University, respectively, and a Ph.D. in Geography, emphasis in water resources, from the University of California at Santa Barbara. In addition to teaching courses in physical geography and research methods, I enjoy advising students and involving them in my various research projects. My ongoing research features a variety of approaches, including field and laboratory methods, as well as computer modeling. Recently, my graduate students have completed a wide variety of projects, including: hydrology and plant growth in natural and constructed wetlands; effects of gas exploration and production on storm water runoff; irrigation practices in urban housing developments; water access in remote regions of developing countries; sustainable use of developed springs; environmental effects of proposed lake impoundments; groundwater pollution from various sources; using aquatic plants to remove contaminants from water; and environmental impacts of producing wind energy. In addition to maintaining an active research program, I serve on several professional editorial boards, advisory panels, and committees in physical geography and geology.
