Short Biography

Dr. Jerad Bales is the U.S. Geological Survey’s Chief Scientist for Water.  Jerad is the USGS Senior Executive re­sponsible for the planning and devel­opment of national basic and applied research programs related to the hydro­logic environment.  He also oversees and evaluates the results of research efforts conducted by universities under the mandates of the Water Resources Research Act of 1984; coordinates the USGS Hydrologic Re­search and Development Program and the Water Resources Research Institutes Program; and assists other USGS lead­ers with external national and interna­tional programs.  Bales represents the USGS on a number of external committees including co-chair of the Subcommittee on Water Availability and Quality (a Federal interagency committee under the National Science and Technology Council’s Committee on the Environment, Natural Resources, and Sustainability), Water Sector lead for the U.S. 2013 National Climate Assessment, member of the National Science Foundation’s Critical Zone Observatory Advisory Board, Chair of the U.S. Committee for the UNESCO International Hydrological Programme, representative to the Region IV WMO Working Group on Hydrology, and as the USGS representative to the GEO (Group on Earth Observations) Water Theme.


Dr. Bales has been principal investigator or Co-PI on numerous water-resources investigations throughout the U.S., as well as internationally.  His research has covered a broad range of topics related primarily to surface-water processes, including small basin studies, flood studies, modeling of rivers, reservoirs, and estuaries,  and research on small stream metabolism.  This work has been funded by more than 20 Federal, State, and local agencies.  Dr. Bales has authored more than 120 articles and technical reports, is invited to speak nationally and internationally and water and climate issues, and has received numerous awards for his government service with USGS.  Prior to his position as Chief Scientist, Dr. Bales was Director of the U.S. Geological Survey North Carolina Water Science Center in Raleigh, NC.  Concurrent with his position with the USGS, he served as Adjunct Professor at the Department of Geography at the University of North Carolina at Chapel Hill, and Visiting Assistant Professor in Forestry and Environmental Studies at Duke University, Durham.
