Dr. Jaffe is an environmental modeler. She earned her Ph.D. in Biology with an Ecology concentration from the University of Toledo. Her research focuses on using various modeling techniques to address questions related to the North American Great Lakes. Recent research includes using Bayesian models to (1) quantify the impacts of climate change on the Great Lakes (2) improve the statistical methods used for measuring harmful algal bloom toxins in Lake Erie and (3) assess the stream conditions associated with the spawning of the invasive grass carp in Lake Erie tributaries. 
Dr. Jaffe teaches courses in the environmental and biological sciences. A goal in her teaching approach is to instill an interdisciplinary perspective in students by emphasizing the interconnectedness of science and society.
