AGU member since 1988. Currently full professor in the Department of Physical Sciences at the Virginia Institute of Marine Science/School of Marine Science, College of William and Mary (W&M). Major research interests include the biogeochemistry and cycling of organic carbon in aquatic and sedimentary systems, with emphasis on applications of lipid biomarkers, stable isotopes, studies of sediment diagenesis, and influence of humans on the carbon cycle in coastal ecosystems. B.S. (1981), Stonehill College; Ph.D. (1992), University of North Carolina at Chapel Hill. Prior to W&M, postdoctoral fellow at U.S. Geological Survey, Menlo Park, California (1992–1994). Member of the American Society of Limnology and Oceanography (ASLO), the Estuarine Research Federation (ERF), Geochemical Society, and the European Association of Organic Geochemists (EAOG). Authored 40+ refereed publications (two in AGU journals), two coedited issues of Organic Geochemistry, coauthor of forthcoming book entitled Chemical Biomarkers in Aquatic Ecosystems. Interests include ocean science education and efforts to expand the participation of underrepresented groups. Director of the NSF-sponsored program Female Initiation into Research, Science and Technology (FIRST), which provided research experiences in marine chemistry/geochemistry for high school girls. Honors include NSF CAREER grant in ocean sciences; Thomas Jefferson Teaching Award (W&M, 2006); Dean's Prize for Advancement of Women (VIMS, 1997 and 2004); Best Paper Award in Organic Geochemistry, Geochemical Society (1997); NRC postdoctoral scholarship (1992–1994); AGU Outstanding Student Paper (1992). Associate Editor for Limnology and Oceanography (2003–2007) and Organic Geochemistry (since 2003).
