The Department of Internal Medicine is made up of 12 academic sections, each with its own administrative structure. Over the past five decades, these sections, through their clinical, educational and research activities, have gained national and international prominence. Most of the sections are housed in The Anlyan Center, a modern research and educational facility providing extensive laboratory, educational and administrative spaces. Clinical activities of the section take place primarily at Yale New Haven Hospital and the Yale Physician Building, both a few minutes walk from The Anlyan Center. The proximity of our sections to Yale School of Medicine has facilitated extensive formal and informal research and educational collaborations with basic science faculty.
