Education

Ph.D. George Mason University, Fairfax, VA 2009
 

David Kersey, Ph.D. is a native Southern Californian. He earned his Ph.D. in Environmental Science from George Mason University and conducted his dissertation research on the reproductive and adrenal physiology of the giant panda at the Smithsonian National Zoological Park.

Professional Experience

He has more than 11 years experience in the use of non-invasive fecal and urinary steroid techniques to assess the reproductive status of diverse wildlife species. While working at the Smithsonian National Zoo, he became among the first to validate enzyme immunoassays for estrogen, progestagen, androgen and glucocorticoid metabolite monitoring in giant panda feces. After developing these techniques he applied them in a comprehensive assessment of hormonal relationships in the female giant panda during estrus, pregnancy, pseudopregnancy, acyclicity and adrenal seasonality; and in the male during seasonal changes in testicular and adrenal function. Dr. Kersey's expertise in giant panda reproduction has been, and is continually sought by US and international giant panda holding institutes to aid in the difficult task of timed breedings/artificial inseminations and during periods of suspected pregnancy. At Western U, he continues his conservation focused research by studying the reproductive biology of other rare and endangered species while still being involved in giant panda reproductive studies.

Committees

Dr. Kersey recently became a member of the newly created American Zoological Association Endocrinology Scientific Advisory Group, a group seeking to support endocrine research among zoological institutions and increase biological information on rare and endangered species. He has also conducted several national and international training courses on the techniques of noninvasive endocrine assessment.

Narrative

In his free time, Dr. Kersey enjoys fishing in the Sierra Nevada, building furniture, and taking his dogs (Iggy, DeeDee and Ollie) to enjoy the local mountains and beaches.
