Research Interests
The major research focus of my laboratory is to investigate the connections between environmental processes and human health. Waterborne disease is a leading cause of morbidity and mortality worldwide. There is little understanding of the population genetics and ecology of these organisms as they move through environmental reservoirs, particularly in freshwater and marine systems. Large freshwater systems, such as the Great Lakes, can act as a both a sink and reservoir. Understanding the parameters that either drive or limit the disease cycle in these systems is critical to delineating the processes that link infected individuals to new hosts through contaminated surface waters.
