Tim D. Braden, PhD Associate Professor of Reproductive Physiology, joined the College of Veterinary Medicine in 1994. Dr. Braden received his B.S. degree in Physiological Sciences from Oklahoma State University. He completed his Ph.D. work in reproductive physiology at Colorado State University. Dr. Braden received a Roy J. Carver Postdoctoral Fellowship to continue his studies in reproductive endocrinology at the University of Iowa College of Medicine. Dr. Braden was a member of the faculty at Oklahoma State University for several years before coming to Auburn University. His research activities have been supported primarily by the United States Department of Agriculture, and the National Institutes of Health. He has served as Associate Editor of the Journal of Domestic Animal Endocrinology since 1995.

Research Interests The main research interests in my laboratory are in the area of reproductive endocrinology. Our overall research is directed at 1) paracrine communication among cells in the reproductive tract, 2) regulatory mechanisms within the cells of the ovary, and 3) long-term reproductive effects of estrogen exposure during neonatal development. Modern cellular and molecular methods are being used to answer questions related to these three areas of interests.
