The Program in Cellular and Molecular Medicine (PCMM) would like to welcome Dr. Hidde Ploegh who has joined the Department of Medicine at Boston Children's Hospital as of December 2016.   Pending completion of his appointment to Harvard Medical School, Dr. Ploegh, who is a former PCMM Scientific Advisory Board member, has been nominated to become a PCMM Investigator and also has been nominated to serve as the first incumbent of a Professorship newly endowed by G.D. Yancopoulos in honor of Frederick W. Alt at Boston Children’s Hospital and Harvard Medical School.  Prior to joining PCMM, Dr. Ploegh was a Professor of Biology at MIT since 2005. Dr. Ploegh is a world-renowned immunologist, cell biologist, and biochemist, who has won many awards for his research. Most recently, Dr. Ploegh was elected as a member of the United States National Academy of Sciences.  His research focuses on molecular immunology, particularly the cell biology and biochemistry of surface proteins relevant for immune recognition. His long-term goal is to establish improved tools to explore the immune response non-invasively and to develop approaches for therapeutic interventions, guided by experiments in the appropriate mouse models.  In the last few years Dr. Ploegh has broadened his research interests to include tumor immunology and immuno-PET to track the impact of antibody-based therapies that target immune checkpoints such as PD-L1.  His current laboratory is located on the 6th floor of the Karp building.
