Meet the Leadership Team

Dr. Caroline DeLong

A Professor of Psychology at the Rochester Institute of Technology (Rochester, NY). She earned her Ph.D. in psychology with an emphasis on human and animal cognition from the University of Hawaii, and completed postdoctoral research at Brown University. She has conducted research with a variety of species, such as dolphins, bats, fish, otters, baboons, orangutans, penguins, and honeybees. She has collaborated with many zoos and aquariums, including a partnership with the Seneca Park Zoo for over a decade. She studies biosonar, visual and auditory perception, tool use, learning, memory, numerosity, and categorization in animals.

Dr. Heather Manitzas Hill

A Professor of Psychology at St. Mary's University, San Antonio, TX, earned her Ph.D. in experimental psychology with emphases in development, cognition, and marine mammal behavior from the University of Southern Mississippi. She has collaborated with many facilities in the USA and around the world. The first 10 years of her marine mammal career involved research on the mother-calf relationship and social development of bottlenose dolphins in human care. In 2007, she added belugas to this research line, and killer whales in 2010. She has also conducted a variety of cognitive projects with large and small dolphins, belugas, sea lions, otters, penguins, and dogs.

She has studied several species of dolphins in the wild and in managed care for over 20 years. She began investigating beluga behavior and cognition in 2011, and in 2012 she added river otter research to her repertoire. Most recently she has become co-director of the SHU Canine Cognition Lab.
