Dr. S. Zev Williams

Professional Interests

Areas of Focus: Miscarriage, recurrent pregnancy loss, infertility.

Zev Williams MD PhD, 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 Research

Miscarriage is the most common complication of pregnancy affecting 1 in 5 pregnancies.  However, in most cases the cause is not known.  Our research utilizes clinical patient samples, cell and animal models to discover new causes of miscarriage with a goal of developing novel diagnostics and therapeutics.


Extracellular RNA

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 ( we are now expanding this research to fully profile exRNAs and utlizing them for non-invasive monitoring of disease.
