Regents' Proceedings 145
Jack L. Kostyo, professor of physiology in the Medical School, will retire from active faculty status on December 31, 1994, after a long and productive career.
A native of Ohio, Professor Kostyo received his AB. degree from Oberlin College in 1953 and his Ph.D. degree from Cornell University in 1957. He pursued further research training at Harvard University, and in 1959 he joined the faculty of Duke University as assistant professor of physiology. He was promoted to associate professor in 1961 and professor in 1966. In 1968, he moved to Emory University, where he served eleven years as professor and chair of the Department of Physiology.
In 1979, Professor Kostyo joined the University of Michigan as professor and chair of the Department of Physiology. As department chair, he played a key role in developing strength in new areas of cellular physiology. Since 1986, he has served as professor of physiology and associate director of the Michigan Diabetes Research and Training Center. A dedicated teacher, Professor Kostyo's enormous breadth of knowledge in endocrinology contributed to his insightful and comprehensive lectures, which were always exceptionally well received. His interest in teaching also led to his involvement in the National Board of Medical Examiners.
Professor Kostyo's research concerns the action of growth hormone on its target cells, particularly muscle and fat, and its role in metabolic alterations associated with diabetes. He is a world-renowned expert on structure-function relationships in the growth hormone molecule, and he also developed a unique animal model to study the diabetogenic effects of growth hormone. Professor Kostyo is a recipient of the Endocrine Society's Ernest Oppenheimer Memorial Award and received an honorary M.D. degree from the University of Gbteborg. He has played leadership roles in a number of scientific societies, including the American Physiological Society and the Endocrine Society, and he served as editor of the journal Endocrinology.
The Regents now salute this distinguished health educator for his dedicated service by naming Jack L. Kostyo professor emeritus of physiology.
