Elizabeth Freeman

Associate Professor

Wildlife conservation, behavioral endocrinology, behavioral ecology

Dr. Freeman joined the School of Integrative Studies as an Assistant Professor of Conservation Studies in 2008. As a conservation biologist, Dr. Freeman studies how to save endangered species from extinction. Such a simplified explanation of her research, however, does little to describe the complexities of this integrative discipline and the problems that conservation biologists try to solve. Like the field itself, her research encompasses a range of topics including behavioral and chemical ecology, evolutionary biology, and reproductive physiology. Behavioral ecology/endocrinology best describe her areas of interest; she conducts studies on the hormones and behavior of the diverse species of this planet.

Her interest in wildlife and passion for protecting biodiversity drive her research endeavors. While she appreciates the need to advance theoretical knowledge, the most rewarding work to her stems from applied studies. Thus, she enjoys conducting research that can improve the reproductive success of endangered species and aid conservation management of wild and captive populations. The work is challenging because all living things are interconnected through their ecology, meaning their success is influenced by their environment and other species. Species’ success is also driven by the foresight and policies of humans; it takes a multi-disciplinary team to fully protect species. Thus Dr. Freeman collaborates with scientific partners from other departments and universities, as well as zoos and governmental agencies.

Dr. Freeman loves what she does. Even more so, she loves sharing her enthusiasm for her research either in a classroom, a peer-reviewed publication or at an international conference. She is frequently reminded of how fortunate she is to have this rewarding career. She strives to conduct ethically sound research that can have a positive impact on the species of this planet.
