Research Interests

Understanding the molecular dialog of early pregnancy, mechanisms of endometrial regeneration, PGRMC1 and PGRMC2 actions in female reproduction and women’s reproductive diseases

Research Summary

My research focuses on understanding molecular events coordinating the physiology of embryo implantation using the mouse and domestic ruminants as model organisms. With a basic understanding of these processes, the long-term goal is to identify mechanisms that, when gone awry, contribute to infertility during early gestation. Related to embryo implantation, we are specifically interested in the processes by which the embryo signals its presence as it invades the uterine wall in an effort to establish an exchange apparatus for nutrients and waste. As progesterone coordinates many of the uterine events during embryo implantation, we are also interested in how ovarian-derived progesterone signals in the endometrium by non-classical mechanisms. We recently demonstrated expression of a novel membrane progestin receptor in the uterus and ongoing studies are designed to test the functional importance of this putative receptor in uterine physiology and pathophysiology. In related studies, efforts are being made to learn how resident stem/progenitor cells of the endometrium contribute to uterine repair during the estrous/menstrual cycle and following parturition.
