Research Interests & Funding

Research in my laboratory focuses on the role of factors produced within the ovary that are essential for ovulation to occur. In the hours just before follicle rupture, the follicle destined to ovulate produces prostaglandins, which act within the follicle to stimulate ovulatory events. Our experiments examine how ovarian prostaglandins are made, where prostaglandins act within the follicle, and which important ovulatory events are triggered by prostaglandins.

By studying prostaglandins and other ovarian factors, we hope our research will lead to better treatments for infertility as well as the development of new contraceptive options.

Current and recent research support comes from NIH/NICHD, CONRAD, the Commonwealth Health Research Board, and the Andrew W. Mellon Foundation.
