National Research Program, Eastern Branch
12201 Sunrise Valley Dr
Reston, VA 20192
I currently serve as Branch Chief for the Eastern Branch of the USGS National Research Program in Reston. The scientists in my Branch conduct research in many fields and on many issues. These include numerical modeling of water flow and solute transport, environmental isotope forensics and characterization, groundwater dating, water and sediment contamination problems, nutrient cycling, ecological habitats, geomorphic processes, and the application of molecular and other techniques to the study of microbial processes. Beyond my Branch responsibilities, I have undertaken a wide diversity of assignments for the USGS. Recently, these have included the advancement of integrated environmental and ecological modeling across a range of organizations and disciplinary interests. My research efforts have focused on geochemical modeling and characterization of groundwater contamination, nuclear waste disposal, and groundwater dating studies. Earlier in my career, I also developed a thermodynamic framework to explain and predict how substitutional impurities affect the solubility and aqueous interactions of mineral phases, and how impurities are released and taken up by minerals. My academic background includes a B.A. (with a major in Geological Sciences) from Columbia College and Lamont Doherty Earth Observatory, an M.Sc. from University of Quebec in Montreal in isotopic environmental geochemistry and the cycling of atmospheric14CO2, and a Ph.D. from the University of Waterloo, where my studies focused on groundwater studies and the thermodynamics of water-rock interactions.
March 2005 – Present: Chief, National Research Program, Eastern Branch. Responsible for managing 100-person Branch and helping set science directions, project budgets, and funding priorities for the $40 Million National Research Program (http://water.usgs.gov/nrp/; the 320-person R&D program for the USGS Water Mission Area). Beyond my leadership and management of the Branch, I support the Bureau through my service for the Research Grade Evaluation Process and through a wide variety of assignments and initiatives (e.g. 3/4D modeling and visualization in the USGS, ecosystem services, support to energy & minerals SSPT, water representative on the Regional Executive and Chief Scientist Team between June 2008 and July 2009). I am also the DOI and USGS representative on a number of Interagency Committees, which include: the Interagency Steering Committee on Multimedia Environmental Modeling, the Carbon Cycle Interagency Working Group (under the US Global Change Research Program Office).
June – Sept. 2004: Acting Chief Scientist for Hydrology. Chief Scientist responsibilities included: participating on the 2nd level 2004 Research Grade Evaluation panel; preparing (and being accountable for) the 2005 National Research Program (NRP) budget; co-leading the 2005 NRP In-depth Project Review and Budget Meeting; numerous interactions with other federal agencies and with the Department of Interior.
Nov. 2001 – Feb. 2005: Staff Assistant to Chief Scientist for Hydrology. Responsible for the Research Grade Evaluation peer-review process in the Water Discipline. Led the USGS National Research Council post-doctoral fellowship program for the entire USGS, establishing science directions and finding funds and opportunities. Program Coordinator in charge of leading the WEBB small watershed program. Water Discipline representative on the USGS Climate Change working group. Helped manage the National Research Program in the Water Discipline. Responsible for assembling science teams in USGS priority areas, and for guiding USGS Water Discipline collaborations with universities.
Jan. 1989 - Nov. 2001: Research Hydrologist, National Research Program. Research interests: Modeling of radionuclide transport and performance assessments for Nuclear Waste Disposal sites (INEEL and Sweden); unsaturated-zone and ground-water geochemical investigations and modeling at Pinal Creek Toxics site, AZ and Äspö Hard-Rock Lab, Sweden; 14C dating of perched waters at Yucca Mountain. Expert in thermodynamics of mineral/impurity/water interactions, in geochemical modeling and in ground-water geochemistry and contaminant transport.
Jan. 1987 – Jan. 1989: NRC Research Associate at the U.S Geological Survey. Competitively awarded National Research Council Postdoctoral Fellowship, National Academy of Sciences. Conducted research on the thermodynamics of mineral/water interactions: created thermodynamic models and predictions of how mineral impurities affect mineral solubilities and how impurities are released or taken up by minerals; tested the models through laboratory experiments and field observations. Research is relevant to many fields and applications, including nuclear waste disposal, contaminant transport, and the chemical evolution of natural waters.
