My research to date has focused on applied conservation questions in aquatic systems, particularly working with freshwater fish, mollusks and macroinvertebrates.  I incorporate field and laboratory approaches to evaluate how organisms, populations, and communities interact with biotic and abiotic stressors in the environment, and to identify basic life history and habitat needs of imperiled aquatic fauna.  These research interests have been consistent since my graduate training here at Warnell, but have benefitted from a seven year career working with the state endangered species program in Massachusetts. 

Because much of my work attempts to ask applied questions, I work very closely with state and federal agencies and other stakeholders to identify questions relevant to management decisions.  That said, my passion is to learn more about the biodiversity of aquatic systems and how species interact with each other.  There is so much to learn about the role species play in freshwater systems, that basic questions of organismal and population ecology are critical to further conservation application.

A note to perspective students:

Some information on some current research projects:

Molecular identification of freshwater mussel - fish host relationships in the Flint River, GA.  This is an exciting project MS student Hayley Robinson is working on with our collaborators at Albany State University, the Flint Riverquarium, and the lab of Dr. John Wares here at UGA.  

Documenting the invasion of the Asian Weather Loach (Misgurnus anguillicaudatus)  in the Upper Oconee River Watershed, GA.  This is a recent project where my colleagues at UGA and I are working to learn more about the distribution, and ecology of a newly introduced species in Georgia.  Much of our work thus far has incorporated undergraduate students in our Fisheries classes, and the UGA Student Subunit of the American Fisheries Society.

Rangewide Restoration Initiative for the Brook Floater (Alasmidonta varicosa).  Since it started in 2016 while I was serving as the Aquatic Ecologist for the Massachusetts Division of Fisheries and Wildlife, I am amazed at the momentum we have gained.  With my Co-PI, Dr. Allison Roy from the USGS Massachusetts Cooperative Fish & Wildlife Research Unit, we developed the Brook Floater Working Group, which contains state and federal agency representation from over 13 states, 2 Canadian provinces, and multiple universities.  We have worked with members of the working group to develop standard survey protocols for use throughout the species range, evaluated genetic differences across populations, assessed the effects of dam removal on Brook Floater habitat, and worked toward population restoration and conservation planning!
