Research or Clinical Activities
My main research objectives are to study the physiological regulation and environmental disruption of male germ cell development, focusing on gonocytes, the precursor cells of spermatogonia stem cells. Disturbance of gonocyte development may lead to infertility or testicular tumors. 听We have identified a number of genes and signaling pathways involved in the regulation of gonocyte proliferation and differentiation, several of which are altered by endocrine disruptors. We are presently studying the interactions between key signaling pathways in gonocytes, as well as the short and long term impact of estrogenic and anti-androgenic endocrine disruptors on testis development. We are also involved in collaborative studies on the regulation of testicular steroid production and the effects of phthalate plasticizers on this process. Lastly, my group is part of a Team grant focused on the development of new innocuous plasticizer compounds to replace phthalates.
