My area of research is reproductive physiology. The regulation of ovarian function is the primary focus of this research, with emphases on the function of the corpus luteum and follicular development. I teach Reproductive Physiology, Advanced Reproductive Physiology, and Graduate Seminar. I have a joint appointment in the Department of Physiology and Cell Biology in the College of Medicine and Public Health.
