Research Interests

My research interests focus on how the metabolic status of women affects their reproductive health. To this end, I have been involved in various projects investigating how endogenous products of metabolism, as well as exogenous compounds, impact ovarian gene expression, steroidogenesis, etc.

Other areas of research in which I am engaged are the structure/function relationship of the reproductive tract to the ovarian cycle, and improving methods to monitor bone mineral density.

The information gained from our studies will enable us to better identify what goes awry leading to female sub-/infertility, understand pathologies effecting fertility such as polycystic ovary syndrome, and how changes associated with aging impact women's health.
