ABOUT US
The Clotfelter Lab at Amherst College is committed to creating an environment in which all students are equally and inclusively supported in their education and research training.
We are broadly interested in animal behavior, physiology, and functional morphology. Most of our current work focuses on a long-term study of tree swallows (Tacycineta bicolor) breeding in Western Massachusetts and on convict cichlid fish (Amatitlania nigrofasciata) in Central America. We also study biomechanics and behavior in crayfish (Procambarus and Faxonius spp.).
