Academic Credentials

Teaching and Clinical Areas

Dr. Rawlings was the associate dean of research at the WCVM until his retirement in June 2010. He also supervised the endocrine service laboratory, which analyses blood and tissue samples from clinicians and researchers for reproductive and metabolic hormones. This lab is part of Prairie Diagnostic Services at the WCVM.

Dr. Rawlings taught general endocrinology and reproduction at the undergraduate and graduate level. In addition, he had an active research laboratory and graduate/postdoctoral training program.

Research Interests

Dr. Rawlings' research interests are in basic and applied aspects of the regulation of ovarian folliculogenesis in sheep and reproductive maturation in beef cattle.
