Degree Year Institution
Ph.D. Hydrogeology 1988 University of Minnesota
M.S. Hydrology 1978 New Mexico Tech

Since 2013, I have been teaching various courses at the University of Arkansas at Little Rock

  • Physical Geology
  • Earth and the Environment
  • Historical Geology
  • Surface Water Hydrology
  • Hydrogeology

Prior to teaching at UA Little Rock, I worked 34 years as a hydrologist with the U.S. Geological Survey, managing a variety of projects during that period including:

  • Characterization of the groundwater flow system of Yucca Mountain, Nevada and
    vicinity (the potential site for a nuclear-waste repository)
  • Analyses of the groundwater flow system and hydrochemistry of coastal sabkhas in
    Abu Dhabi, United Arab Emirates
  • Groundwater modeling of flow systems in Arkansas, as well as Oklahoma, Kansas,
    and Missouri

Research Interests

My research interests include:

  • Changes in fractured-rock hydraulic properties as a result of thermally enhanced
    pressure dissolution
  • Hydrochemical and physical properties of groundwater and surface water
  • Groundwater flow modeling
  • Sustainability of water resources
  • Meteorological instrumentation
  • Urban hydrology
