Elizabeth Hamman
Elizabeth Hamman
Dr. Hamman received her BA in Marine Biology/Applied Math from New College of Florida, and her Ph.D. from the Odum School of Ecology at the University of Georgia. She completed postdocs in the Biology Departments of East Carolina University and Radford University, and the Math Department of Tulane University.
Generally, she's interested in how interactions between organisms generate spatial variation, particularly when one of the organisms forms biogenic habitat. She also enjoys thinking about predator-prey dynamics and statistical methods.
