Education:
B.S., Resource Ecology and Management, University of Michigan Ann Arbor, 1999
B.S., Philosophy, University of Michigan Ann Arbor, 1999
Ph.D., Marine Science, The College of William and Mary, 2006

Employment:
2009-Present      Research Biologist, U.S. EPA National Health and Environmental Effects Research Lab, Mid-
                  Continent Ecology Division, Duluth, MN

Research Interests and Skills:
Broadly, I am interested in how human-caused changes to the environment influence aquatic ecosystem processes,
habitat, and fish population success. I believe my research should support development of a workable practice of
sustainable ecosystem-based management. Specifically, my research goals are to understand how changes in
ecosystem function relates to food web function, particularly the exchange of nutrients, matter, and organisms
between ecosystems; to examine relationships between ecosystem function, habitat quality and fish recruitment; and
to develop survey tools to quantify the value of aquatic habitats to fish. My research is focused on coastal and
estuarine fishes because they are of economic and social importance and because their habitat is highly vulnerable to
anthropogenic impacts.

Professional Societies:
Phi Beta Kappa
American Fisheries Society
American Society of Limnology and Oceanography
Estuarine Research Federation
