Areas of Focus: Miscarriage, recurrent pregnancy loss, infertility.
Zev Williams MD PhD, is the Director of the Program for Early and Recurrent Pregnancy Loss (PEARL). He is Board Certified in Obstetrics and Gynecology as well as in Reproductive Endocrinology and Infertility. Dr. Williams completed his residency in Obstetrics and Gynecology at the Brigham and Women's Hospital/Massachusetts General Hospital at Harvard Medical School and his fellowship in Reproductive Endocrinology and Infertility at Weill-Cornell. His clinical and research focus is infertility with a special emphasis in helping those suffering from recurrent miscarriages.
Miscarriage is the most common complication of pregnancy affecting 1 in 5 pregnancies. However, in most cases the cause is not known. Our research program is focused on discovering causes of miscarriage and developing novel therapies to prevent miscarriage.
We recently comprehensively and quantitatively profiled microRNAs in circulation and were able to demonstrate tissue-specificity in origin of the microRNAs. Using the placenta as a model, we were further able to show that the microRNA fingerprint was sufficient to match the microRNA signature in a particular serum sample with the placenta from which the microRNAs were derived. As part of the NIH extracellular RNA (exRNA) consortium (http://exrna.org) we are now expanding this research to fully profile exRNAs and utlizing them for non-invasive monitoring of disease.
