Current Research

I investigate how environmental factors impact biodiversity in freshwater ecosystems. I conduct research on freshwater aquatic organisms and ecosystems, focusing on fish and crayfish in streams of the southeastern United States. My research focuses on understanding the relationship among fish, crayfish, and their environment, as well as how disturbances, both natural and anthropogenic, impact these relationships. Because basic life history data is not available for numerous aquatic species, I also conduct studies to improve the life history and distributional knowledge of crayfishes.

Research Interests

Aquatic animal Habitat usage, community structure, and gene flow

The effect of human degradation and climate changes on aquatic animal habitat, habitat usage, community structure, and gene flow
