More About

Dr. Wares has a joint appointment in the Odum School of Ecology and the Department of Genetics, Franklin College of Arts and Sciences.

Research Interests

I study gene flow and molecular evolution in natural populations with a particular interest in examining the effects of asymmetric dispersal. Although the approaches I use would fit wind-dispersed and riverine species, most of the work in my lab is on marine species, with barnacles being one of my favorite groups. The dispersal of marine larvae has the potential to add to our understanding of how physical and environmental forces lead to the balance of diversity we see in coastal communities.
