Research Wildlife Biologist

Primary Responsibilities: 
Research duties include investigations of coastal wetlands and their associated waterbird populations, assessing potential effects of sea-level rise on coastal wetlands and bird habitats, evaluating the ecological effects of marsh management techniques on federal refuges and parks, monitoring island restoration methods and wildlife responses, investigating the role of migratory waterbirds in the avian influenza threat, and providing technical assistance to land managers on decisions involving wetland habitat manipulations, restoration, or enhancement.

Current projects include:  (1) assessing the long-term changes along the Virginia Coast Reserve and the implications to waterbird populations and habitats (co-PI with the University of Virginia’s Long Term Ecological Research Project); (2) evaluating island restoration techniques in Chesapeake Bay with respect to waterbird population dynamics (with focus on Poplar Island Environmental Restoration Project); (3) conducting research on the role of migratory birds in transmission of avian influenza in China (SCEP student involvement); (4) monitoring effects of sea-level rise in coastal Virginia and potential impacts on waterbird habitat; (5) senior editor of symposium proceedings on “Waterbirds of the Chesapeake Bay and Vicinity: Harbingers of Change,” Waterbirds 30 (Special Publication 1), 2007.
