Full Curriculum Vitae

PROFESSIONAL INTERESTS:

David Shafer is the Director of the Frank H. Rogers Center for Environmental Remediation and Monitoring that includes DRI’s Technical Research, Engineering, and Development Services (TREDS) Contract for the U.S. Department of Energy (DOE) and National Nuclear Security Administration. His previous work experience includes environmental restoration and environmental, safety and health work for DOE, environmental interpretation and natural resources management for the U.S. National Park Services, and teaching at Colgate University and for the Hancock Natural History Field Station of the Oregon Museum of Science and Industry.

His current research interests include soil morphology and hydrology of arid regions; adaptive management and long-term stewardship of contaminated groundwater and other sites with risks that remain after regulatory closure; environmental radioactivity and its use in nuclear openness initiatives for non-proliferation; stakeholder involvement in environmental monitoring and management; and use of analog sites and Quaternary science climate and environmental reconstructions as the basis for environmental remediation, reclamation, and natural resource management.
