Bobbi Peckarsky is an Honorary Fellow in the Biology Department and an Adjunct Professor of Entomology at the University of Wisconsin- Madison. She is also Professor Emeritus of Entomology and Ecology & Evolutionary Biology at Cornell University, where she spent over 25 years studying the fascinating interactions between stream-dwelling organisms and their environments. She was the first female faculty member hired in Cornell’s Entomology Department, in 1979.

Bobbi research focuses on predator-prey dynamics, invertebrates as indicators of water quality, and how disturbance and climate change affect freshwater ecosystems. She has conducted extensive field studies on stream ecology at the Rocky Mountain Biological Laboratory and has been recognized internationally for her contributions to ecology. Beyond academia, Bobbi has championed the health of freshwater ecosystems by serving on several environmental boards and advisory councils.
