Dr. Peter Sorger

Dr. Peter Sorger is the Otto Krayer Professor of Systems Pharmacology at Harvard Medical School. Prior to HMS, he served as a Professor of Biology and Biological Engineering at MIT. He was cofounder of Merrimack Pharmaceuticals and Glencoe Software and is an advisor to multiple public and private companies and research institutes in the U.S., Europe and Japan.


Dr. Sorger’s research focuses on the signal transduction networks controlling cell proliferation and death, dysregulation of these networks in cancer and inflammatory diseases, and mechanisms of action of therapeutic drugs targeting signaling proteins. His group uses systems biology approaches to seek to understand and predict cell and tumor responses to both individual and combinations of drugs. The Sorger group also develops open-source software for analyzing biological networks and drug mechanism of action, and it participates in multiple collaborative programs working to improve data access and reproducibility.


As founding head of the Harvard Program in Therapeutic Science (HiTS) and its Laboratory Systems Pharmacology (LSP), Dr. Sorger leads a multi-institutional effort to advance the basic and translational science used to develop new medicines, create novel drug combinations and identify responsive patients.


He received his AB from Harvard College and PhD from Trinity College, Cambridge University U.K., working under the supervision of Hugh Pelham. Dr. Sorger trained as a postdoctoral fellow at the University of California, San Francisco, with Harold Varmus and Andrew Murray.
