Short Biography

Entered service with the Department of Interior in the summer of 1969 as a Trail Crew I for National Park Service in Kings Canyon National Park, and after completing a doctorate in the College of Natural Resources UC Berkeley, became a Research Hydrologistfor the National Research Program within U.S. Geologial Survey in 1980 at the Palo Alto (CA) Deer Creek facility, carrying out both laboratory and field research on the influence of temperature on shallow transport properties and processes, and eventual pioneering the use of heat as tracer to examine stream exchanges with shallow groundwater.

Stream exchanges with groundwater

Research focuses on the use of heat and other natural tracers to advance our knowledge of stream and other surface-water exchanges with shallow groundwater, with an emphasis on the physical, chemical and biologic impacts of these exchanges on streambeds and other shallow sediments in reference to overall water and biologic resources in watersheds.
