Stephen C. Blacklow, M.D., Ph.D.

Dr. Stephen Blacklow currently serves as an MPM Advisor. Stephen is the Gustavus Adolphus Pfeiffer Professor and Chair of the Department of Biological Chemistry and Molecular Pharmacology at Harvard Medical School, and a member of the Department of Cancer Biology at the Dana Farber Cancer Institute.

Research by Stephen’s team has furthered the understanding of how cells can communicate with one another and cause each other to undergo downstream changes, which is an important mechanism in many cancers. His research on the Notch pathway has led to the development of new investigational therapies for hematologic malignancies such as T cell ALL.

Of his many other awards and professional affiliations, Stephen received the National Cancer Institute’s prestigious Outstanding Investigator Award in 2017 and was elected to the Association of American Physicians in 2018. Stephen also directed the MD-PhD Program in Basic and Translational Sciences at Harvard Medical School and has served on Advisory Committees for pre-clinical departments, graduate programs, and MD-PhD programs at several major research universities and institutions, including Stanford, the University of Pennsylvania, and the Memorial Sloan Kettering Cancer Center.

Stephen earned his M.D. and Ph.D. from Harvard University in 1991. He completed his residency in Clinical Pathology at Brigham and Women’s Hospital and conducted his postdoctoral research at the Whitehead Institute with Dr. Peter S. Kim.

In 2009, he became the Clinical Director of the MGH Cancer Center and in 2012, became Chief of the MGH Cancer Center. His clinical practice focuses exclusively on gastrointestinal oncology.

David graduated in medicine from Columbia College of Physicians and Surgeons, New York, NY in 1992 where he remained for his internship and medical residency. He is a member of the American Association for Cancer Research (AACR), American Society of Clinical Oncology (ASCO) and the New England Cancer Society. He has published over 50 articles in peer review journals, reviews, book chapters and editorials, and authored numerous abstracts.

H. Robert Horvitz, Ph.D.

Dr. H. Robert (Bob) Horvitz has been an Advisor to MPM since 2005 and has served as the Chairman of MPM’s Advisory Boards since 2007.

Having joined the Massachusetts Institute of Technology’s Department of Biology faculty in 1978, he was named the David H. Koch Professor of Biology in 2000. He was appointed a Member of the Koch Institute for Integrative Cancer Research in 2000 and a Member of the McGovern Institute for Brain Research in 2001. He is a member of the Board of Trustees of the Massachusetts General Hospital.

Bob received the 2002 Nobel Prize in Physiology or Medicine for discovering and characterizing genes that control programmed cell death (apoptosis), findings that have provided the basis for understanding many aspects of human biology and disease.

Bob is a member of the U.S. National Academy of Sciences, the U.S. National Academy of Medicine, the American Academy of Arts and Sciences, the American Philosophical Society, and The Royal Society of London. He is a recipient of the Gairdner Foundation International Award, the Alfred P.
