Professional Experience

United States Geological Survey, Chesapeake Bay Coordinator (October 1995 to present)

  • Serves as coordinator and liaison for USGS activities involved with management and restoration of the Chesapeake Bay and its watershed. Primary duty is coordination of the USGS Chesapeake Bay Studies, which involves about 30 USGS projects. Acts as the primary USGS liaison to the Chesapeake Bay Program by serving on several the Subcommittees (Implementation, Monitoring, and Scientific and Technical Advisory) and workgroups (Nontidal Tributaries, Chair; Sediment, and Water Quality Technical workgroup). Integrates the USGS findings with other Federal and State agencies and academic institutions involved in the Bay restoration.

United States Geological Survey, Water-Quality Specialist (January 1991 to October 1995)

  • Served as technical specialist in all matters pertaining to quality of water conducted by USGS with the Mid-Atlantic area. Provided direct technical support to approximately 45 interpretive projects including project planning, formulating monitoring and data collection approach, data interpretation, and report review. Participant in the Chesapeake Bay Program through membership on monitoring subcommittee and associated workgroups. Provided communication and exchange of technical information between USGS and other agencies.

Geraghty and Miller, Inc, Senior Scientist (November 1989 to December 1990)

  • Served as Groundwater group leader, project manager, and principle investigator for a variety of Groundwater and hazardous-waste projects. The projects included CERCLA Hazardous Waste Remedial Investigations, RCRA Post-Closure Permit studies; water-supply and well-field design studies, characterization of Groundwater flow and quality underlying landfill sites, and environmental assessments.

United States Geological Survey, Hydrologist (December 1983 to November 1989)

  • Principle investigator for hazardous-waste characterizations, Groundwater flow modeling, and Groundwater supply and quality projects in Maryland and Delaware. Projects included study of Groundwater/surface-water interactions, contaminant transport, and low-temperature aqueous geochemistry.
