She researches echolocation in toothed whales, dolphins, and bats. Specifically, in toothed whales and dolphins, she investigates how individuals adapt their sonar beams, and in bats, she investigates swarming acoustics and flight behavior of large caves and colonies. As a former high school biology teacher, Kloepper is also passionate about connecting students with scientists and encouraging hands-on bioacoustics research. She launched soundintheclassroom.org, which provides resources and lesson plans for students to conduct quantitative, inquiry-based bioacoustics investigations using free, open-source software. Follow her and her students (on their Blog or on Twitter) this summer as they embark on a 5,000 mile journey to visit bat caves across the Southwestern United States!
