Research Interests

I am interested in the evolutionary forces that shape the geographic patterns of genetic variation within a species, and often this work blends into the areas of systematics and conservation. While much of the research in my lab focuses on fishes, my research program tends to be more question-oriented as opposed to organism specific. Currently we are working on projects that are focused on the biota of the southeastern United States (including freshwater fishes and gopher tortoises). Students working in my lab over the years have pursued a broad array of interests including blue crabs, pythons, anadromous fishes, freshwater turtles, Central American fishes and invasive plants. While the organisms are diverse, the common theme is the study of geographic patterns of genetic variation.
