Pete Guiden is a community ecologist, studying the interaction of living things. An important component of this research is understanding how humans alter these interactions through climate change, habitat loss, and introducing invasive species. A large part of Guiden’s research focuses on the ecology of seeds—where they go, who eats them, and how many survive to adulthood. 

Before coming to Hamilton, Guiden was a postdoctoral fellow at Northern Illinois University. He received a Ph.D. in integrative biology from the University of Wisconsin-Madison, a M.S. in botany from Miami University, and a B.A. from Wabash College. Guiden enjoys bringing his research into the classroom, especially the chance to involve students in the effort to conserve and restore biodiversity on campus.
