McCracken is a field biologist who applies molecular tools and innovative field techniques to investigate questions concerning the ecology, behavior, and evolution of bats, and occasionally other animals. His research on bats has concerned mating systems, social behavior, communication, and relatedness. He also has investigated foraging and flight behaviors, links to high altitude insect migrations, and the ecosystem services of bats. His work on disease ecology has concerned diseases that bats can give to humans (rabies) and disease that humans give to bats (white-nose syndrome). For four decades, Gary, his students, and colleagues have repeatedly returned the Brazilian free-tailed bat (Tadarida brasiliensis) as a “magic well” of continuing significant and surprising discoveries.
McCracken has received numerous honors, including the Gerrit Miller Award for his contributions to research on bats, the James R. Cox Professorship, the Alexander Prize, and the Macebearer Award, the highest faculty honor given at his University. He is an elected Fellow of the American Academy for the Advancement of Science. He served as EEB Department Head from 2008 – 2014.
