  • B.S., Bucknell University
  • Ph.D., University of Virginia
Research Interests

My primary research interests are in tidal and nontidal wetlands ecology, landscape ecology and resource management/policy issues. I have active interests in resource inventory procedures, habitat restoration protocols, resource management "expert system" development, and science-policy interactions. Much of my current activity involves integrated resource management and the development of supporting scientific rationale. This work involves collaboration with colleagues in other disciplines and is presently focused on coastal watershed management.

Current Projects
  • Structure and function of nontidal wetlands in the coastal plain
  • Watershed management in the York River Basin
  • Resource use conflict analysis and policy development
  • Landscape level habitat suitability model development
  • Shoreline management policy development
Current Students
  • Mary Huang, Ph.D. - Mary is a Ph.D. candidate investigating the role of tidal wetlands as a source of fecal coliform by analyzing the model predicted erros between observed data and water quality model predictions. The results of this work may have an impact on the development of shellfish total maximum daily loads (TMDLs) in Virginia.
  • Karinna Nunez, M.S. - Karinna is a MS candidate for the College of William and Mary/Virginia Institute of Marine Science. She is developing a Multi-level Erosion Risk Assessment Model to evaluate the vulnerability of Maryland shoreline due to erosion. She is utilizing different levels of forecasting to assess potential shoreline change. While pursing an advanced degree, Karinna also works for CCRM as a GIS Programmer. Her research interests include GIS technology and remote sensing, sustainable development management in coastal areas, and water quality issues.
  • David O'Brien, Ph.D. - David is a Ph.D. candidate for the College of William and Mary/Virginia Institute of Marine Science. While pursuing an advanced degree, David also works for CCRM as the Program Manager for the wetlands advisory group. His interests include the development of ecological indicators of aquatic health for tidal and nontidal wetland ecosystems, the study of tidal and nontidal wetland plant communities and shifts in plant assemblages resulting from changes in salinity, elevation, and the frequency and duration of flooding associated with climate change.
