Professional Focus
Dr. Zhang focuses on investigating the anthropogenic impacts on the interactions among trophic levels in freshwater and marine ecosystems by constructing and applying statistical and ecological models. Based on the two-dimensional CE-QUAL-W2 model, she has constructed EcoLE, an ecological model of Lake Erie. The model has been used in studying the impacts of zebra mussels and quagga mussels on plankton, evaluating the phosphorus reduction program on Lake Erie, and investigating the occurrence of blue-green algal blooms. Dr. Zhang is also actively involved in studying the impacts of hypoxia on the living resources in the Northern Gulf of Mexico and the central basin of Lake Erie using statistical and ecosystem-based models. Currently, Dr. Zhang is engaged in using ecosystem-based models to investigate the impacts of invasive species on the Great Lakes. All the research has aimed to assist fisheries and water quality management.
