Gerry Carter is studying the cognitive and behavioral ecology of cooperative relationships. He is a Humboldt Fellow and was previously a Smithsonian Postdoctoral Fellow at the Smithsonian Tropical Research Institute and a Ford Predoctoral Fellow at the University of Maryland. Gerry is working to develop food-sharing vampire bats as a tractable experimental model for studying how individuals choose and regulate cooperative relationships. He is currently analyzing data from a 22-month experiment with vampire bats that (1) measured how food sharing developed between previous strangers housed together in captivity, (2) manipulated new and old relationships by changing partner behavior, and (3) tracked roosting and foraging association in the same bats released back into the wild. Gerry is now an Assistant Professor at The Ohio State University – see https://socialbat.org.
