Research Interests

Ecological Modeling, Stakeholder Engagement, Estuarine Ecology, Chesapeake Bay, Marine Policy, Population Assessment

Educational Background

I earned both my Master’s and PhD in Marine Science at the Virginia Institute of Marine Science, at the College of William & Mary.  My post-doctoral studies were completed with the University of Maryland Center for Environmental Science, at the Chesapeake Biological Laboratory.

Biographical Sketch

I am a quantitative fisheries scientist specializing in applied estuarine fisheries ecology. Most of my work has been focused on the Chesapeake Bay, and providing resource managers with the quantitative metrics they need to make well-informed policy choices.  I am especially interested in the tension between development and conservation of critical fisheries habitats in a context of increasing coastal population growth and shifting climate trends, and in estimating the cumulative impacts of simultaneous stressors on the ecosystem services our aquatic ecosystems provide under different management strategies.
