VomachkaDr. Archie J. Vomachka

Dean of the College of Health Sciences
Professor of Biology

Dr. Vomachka received his B.A. in Biology from the University of Minnesota, Duluth, and a Ph.D. in Zoology from Michigan State University (1976). Following a postdoctoral fellowship in reproductive physiology at the University of Kansas Medical Center, he began teaching in 1979. Faculty assignments included positions at Princeton University and Marquette University prior to coming to Arcadia University in 1988 as Associate Professor of Biology. Dr. Vomachka was the Chair of the Department of Biology from 1989-2001 and 2005-2006. He was promoted to the rank of Professor in 2000. After 23 years in the Biology Department, Dr. Vomachka was appointed Founding Dean of the College of Health Sciences in July 2011.

Dr. Vomachka's research interests may be broadly categorized in the area of endocrine physiology. Recent work in collaboration with Dr. ND Horseman at the University of Cincinnati focuses on the hormone prolactin, its interaction with reproductive steroids, the regulation of mammary gland development and function in mice, Humans, and cows. References for recent articles and links to some of them are listed below.
