DR. WAYNE J. KUENZEL Physiologist/Neurobiologist

Dr. Kuenzel received his B.S. and M.S. degrees in biology from Bucknell University in Lewisburg, Pennsylvania, and his Ph.D. in zoology from the University of Georgia. He served two years in the U.S. Army at Ft. Sam Houston, Texas, where he was an instructor and chief, Basic Sciences Branch, U.S. Medical Field Service School. He obtained a National Institutes of Health Postdoctoral Fellowship and spent two years at Cornell University studying avian reproductive physiology, followed by a third year as a research associate in poultry nutrition. Dr. Kuenzel joined the Department of Animal and Avian Sciences at the University of Maryland in 1974 as an Assistant Professor of Physiology. He was promoted to the rank of Associate Professor and Professor in 1978 and 1984, respectively. Dr. Kuenzel's research addresses the neural regulation of early sexual maturation, broiler breeder reproductive behavior and stress. He was awarded a Fulbright-Hays Senior Research Fellowship to Scotland, U.K. (1981), and Germany (1988), which were applied to sabbatical years spent in Europe. Dr. Kuenzel was awarded the Poultry Science Association Purina Teaching award (1988); the Merck Award for Achievement in Poultry Science (1998); the Agriculture Research Award of Gamma Sigma Delta, (1999), University of Maryland; and the Sigma Xi Research Award, University of Maryland, (2000). Dr. Kuenzel joined the Center of Excellence for Poultry Science, University of Arkansas, in June of 2000. RECENT PUBLICATIONS Jurkevich, A., L.R. Berghman, L.E. Cornett and W.J. Kuenzel. 2008.
