After finishing his undergraduate studies at Brown University, Dr. Sutton enrolled in the MSTP at Stanford, where he obtained his PhD degree with Dr. John Boothroyd, working on trans-splicing in African trypanosomes. He then completed a categorical residency in internal medicine at the Hospital of the University of Pennsylvania and a fellowship in infectious diseases at UCSF. After post-doctoral stints with Drs. Harold Varmus, Dan Littman, and Pat Brown in which he worked on HTLV cell binding and entry and the development of HIV-based gene therapy vectors, he joined the faculty at Baylor College of Medicine. In 2008 he was recruited to Yale to continue his work on HIV replication and lentiviral vectors. Dr. Sutton spends approximately 50% of his time at the research bench and 25% in the clinical setting, both out-patient and in-patient, mainly at the West Haven VA (VACT). He is also the chief of Infectious Diseases at VACT, which takes up 25% of his time. Dr. Sutton took an administrative leave of absence in mid-April 2022, but he resumed all of his clinical, educational, and research activities before the beginning of 2023.
