My primary research interests are in the role that ecological processes play in structuring aquatic communities and their implications for the population dynamics of marine and estuarine fishes. I am interested in identifying factors that affect vital rates of different life history stages and extending knowledge of individual processes to understand interactions among size-structured populations. The population dynamics of the juvenile stages of many fishes are poorly understood and recent evidence has indicated that processes occurring during the first year of life post-metamorphosis can result in a significant bottleneck between larval stages of fishes and recruitment to the adult population. Recently, my research has been focused on the population ecology of southern flounder, including the sources and magnitude of natural and harvest mortality, migration dynamics, and population connectivity.  In addition, we have ongoing investigations of recruitment mechanisms contributing to variable year-class strength in red drum, contingent behavior in riverine striped bass populations, and the trophic impacts of invasive catfishes in coastal systems.
