Education

  • 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
