Academic Interests and Accomplishments:
Dr. Hays pursues research in application of stable isotopes and other geochemical indicators in delineating movement and behavior of contaminants in ground-water systems and in characterizing paleoclimate and paleoenvironment. In addition, Dr. Hays serves as Ground Water Specialist for the interagency Natural Resources Conservation Service National Water Management Center, providing assistance in ground-water hydrology and geochemistry to U.S. government entities in the U.S. and abroad; this work involves University of Arkansas students in such diverse research areas as mercury contamination in the Guianas Ecoregion, radionuclide contamination in thermal springs of Hot Springs National Park, and salt-marsh restoration in coastal New England.
