Research Focus

As a conservation biologist, I am most interested in applied research that focuses upon how to save endangered species from extinction. The main focus of my research is behavioral endocrinology, which broadly means I investigate how the [internal and extrernal] environment affect the hormones and behavior of species. My projects have a wide-ranging scope from animal behavior, to chemical ecology, evolutionary biology and reproductive, stress physiology. My expertise and the majority of my work has been on mammals, but I welcome collaborations on any taxonomic group. I have experience working with the captive community as well as conducting field work in Africa and have advised graduate students on field projects in Asia and South America. I collaborate with scientific partners from other departments and universities, as well as zoos and governmental agencies. My overall goal is to conduct ethically sound research that can have a positive impact on the species of this planet.
