My research explores the dynamics of fish populations and the impacts of fishing. One on-going project, based in Uganda, explores the relationships between civil conflict, food prices and security, fishing behavior, and fish abundance in the major commercial fisheries of Lake Victoria. As part of this project, I am engaged with the National Fisheries Resources Research Institute (NaFIRRI) in Uganda to establish a collaborative Geographic Information Systems research and education center. This center will host W&M students for summer research projects and will provide continuing education and training of NaFIRRI scientists in GIS. I approach the study of fisheries from a dynamic systems perspective, using nonlinear forecasting models to classify and predict fish abundance and to understand the impact fishing has on population dynamics. I also use time series approaches to ecological modeling to study the relationships between predators and prey, fish and the environment, fishing and fish abundance, and spatial distributions of populations. Finally, I specialize in predator-prey dynamics of marine fishes, including gut content analysis, modeling, and bioenergetics.
