Sara Bouberhan, MD, Gynecologic Medical Oncology
Dr. Bouberhan’s research is focused on identifying blood-based biomarkers in ovarian cancer. She is currently working on a project to detect patient-specific p53 mutations in plasma using droplet-digital PCR. This project relies on an ongoing collaboration with the Gyn Tissue Repository. Banked specimens from patients’ initial surgical resection are accessed to identify tumor-specific DNA sequences. These sequences are then used to develop customized DNA sequencing primers and detection probes which are applied to blood samples. Blood collected through the tissue banking protocol at the time of patients’ initial surgery is used as a substrate to identify circulating tumor DNA. Dr. Bouberhan also collaborates with the tissue repository team to prospectively collect blood and ascites specimens to support this and future projects.

Alexander Melamed, MD, MPH
Alexander Melamed, MD, MPH, focuses his research on the evaluation of the effectiveness of health care service, with an emphasis on the role of surgery in improving outcomes among women with gynecologic cancer. To overcome the challenge of unmeasured confounding when attempting to estimate causal association in observational data, Dr. Melamed employs sophisticated analytic methods including acyclic graphs, propensity score methods, and quasi- experimental study designs. His studies have been published in the New England Journal of Medicine, JAMA, BMJ, and high impact cancer journals. Dr. Melamed is currently on the management committee of the Laparoscopic Cytoreduction After Neoadjuvant Chemotherapy (LANCE) trial, an international integrated phase III/pilot randomized trial designed to assess the efficacy of minimally invasive surgery for interval cytoreduction of advanced ovarian cancer.
David Pépin, PhD
Dr. Pépin’s laboratory studies female reproductive development, and particularly how the TGF-b superfamily of hormones regulates ovarian and uterine formation and subsequent functions. His group focuses on Anti-Mullerian Hormone, aka AMH, and the mechanisms by which it controls ovarian folliculogenesis. Discoveries regarding AMH and other related hormones are being translated to the clinic, with the development of a new class of contraceptives, infertility treatments, drugs protecting the fertility of children and women receiving chemotherapies, and even treatments for ovarian cancer. Importantly, his team is developing multiple treatment strategies, from biologics, to gene therapies, and high-throughput drug screens to address unmet needs in women’s health.
Andrea Russo, MD, Gynecologic Radiation Oncology
As Director of the Gynecologic Radiation Oncology Program at MGH, Andrea Russo, MD, dedicates her time and skills to the care of patients with gynecologic cancers. Dr. Russo is also an Assistant Professor at Harvard Medical School. She is actively engaged in clinical and translational research to improve patient outcomes.
With Dr. Russo's expertise in the latest radiation technologies including brachytherapy, IMRT/VMAT, and proton therapy, she is committed to providing the highest quality of evidence-based and compassionate care.
Steven Skates, PhD
Dr. Skates has been dedicated to studying early detection of ovarian cancer including biomarker discovery and validation. He spearheaded development of multiple longitudinal early detection algorithms which were implemented in five prospective early detection clinical trials. More specifically, Dr. Skates risk of ovarian cancer algorithm has been implemented in a definitive trial of 200,000 postmenopausal women with half screened annually for up to 11 years and with ovarian cancer mortality as the “gold standard” endpoint. Dr. Skates has served as a co-investigator for multiple proposal s led MGH, BWH and DFCI based investigators on identification and validation of biomarker(s) for ovarian cancer detection. He is recruited by Gyn ORC members to develop statistical models for proposed research applications.
David Spriggs, MD, Gynecologic Medical Oncology
Dr. Spriggs’ research is focused on cell membrane glyco-proteins that promote the patho-biology of ovarian cancer. The serum marker, CA125, has been used to manage ovarian cancer since the 1980’s but its function(s) have yet to be completely identified. CA125 is the cleaved portion of the tethered mucin MUC16. The Spriggs Lab have provided insights into the function of MUC16.
It is now apparent that MUC16 regulates growth, invasion and metastatic disease disease through the structure of sugars (glycosylation) on the surface of normal and cancer cells. This regulation requires interaction with specialized sugar binding proteins, Galectins, which are key components of the tumor microenvironment. We are actively developing antibodies against MUC16 and Galectin 3 for diagnosis, imaging and treatments. Our work has shown that antibodies which inhibit these cell – cell interactions can slow tumor growth and inhibit metastasis.
Cheng Wang, PhD
Dr. Wang’s group focuses on the identification of key regulatory proteins in the Hippo-Yap signaling pathway that regulate the normal physiology of the cervix and ovary. More importantly his team is defining how aberrant Hippo-Yap signaling can promote malignant transformation, invasive and metastatic properties.
Recently, Dr. Wang has shown that increased Yap signaling can promote an immunotolerant environment. Delineating the mechanisms by which Yap promotes immunotolerance will allow for the development of novel treatment strategies to overcome this tumor resistant micro-environment. To accomplish these goals Dr. Cheng’s lab develops novel transgenic mouse models to determine the functional contributions of the members of the Hippo-Yap signaling pathway in cervical and ovarian cancer.
Oladapo Yeku, MD, PhD, FACP, Gynecologic Medical Oncology
Dr. Yeku’s research efforts are focused on delineating the functional contributions of the tumor microenvironment. Specifically, he and his team are designing and testing immunologic approaches for the management of ovarian cancer. His research utilizes syngeneic immune competent mouse models of metastatic ovarian cancer with subsequent validation in appropriate genetically engineered and xenograft models. This approach allows for analysis of the effects of this combinatorial therapy in recruiting and harnessing the hosts’ effector immune cells against cancer cells. Furthermore, this approach allows critical evaluation of the immunosuppressive cytokine, cellular and tumor microenvironment in response to therapy.
