Current Research
My research focuses on developing management and conservation strategies for freshwater mussels and warmwater fishes based on a holistic understanding of the life history and ecology of these organisms. Forest lands in the southeastern U.S. support some of the most diverse, but threatened aquatic ecosystems in the world. Current management and conservation efforts are hampered by a lack of information about the ecology of most species that compose these ecosystems. My research program is geared toward generating solid life history information on aquatic species then integrating this information to produce useful ecological models. I am particularly interested in how suites of life history traits influence community assembly, population dynamics, and responses to ecosystem change. I am applying research findings toward evaluating potential outcomes of management actions, and development of repeatable monitoring programs that can simultaneously provide an assessment of population viability.
