Research Interests: 
For the last 20 years I have been funded by NIH, the March of Dimes, and the Burroughs Wellcome Fund for studies of fetal membrane biochemistry and biomechanics. These studies have focused on correlation of the mechanical properties of the fetal membranes with biochemical characteristics. Specifically, I have developed an ex-vivo model system using human fetal membranes to study the details of the weakening process fetal membranes go through to rupture in response to inflammation/infection and decidual bleeding. This has led to our finding that GM-CSF is the critical intermediate that is both necessary and sufficient for inflammation/bleeding induced fetal membrane weakening. In addition, we have studied the effects of possible inhibitors of the weakening process and demonstrated how each agent blocks GM-CSF production, GM-CSF downstream action or both. We have been concerned that our research to date implies that minor local inflammatory challenges could result in fetal membrane rupture and preterm birth.  Some mechanism to push back against this process seemed necessary. Our new data suggests a progesterone mediated, inducible negative feedback system exists locally at the fetal-maternal interface. We are very excited to explore the ramifications of this. A NIH RO1 Grant submitted June 2020 and is pending review.
