On behalf of the faculty and trainees of the Department of Internal Medicine at Yale School of Medicine, I would like to welcome you to our website. We are eager to help you learn more about our department’s rich array of programs in research, clinical care, and education.

The Yale Department of Internal Medicine strives to provide outstanding, compassionate, and equitable care to our patients. 

We are dedicated to the development of new knowledge through innovative basic biomedical discovery and rigorous clinical research, and to translating these discoveries into novel therapies.

We aspire to train and inspire the next generation of leaders in medicine through education that fosters creativity and a personal commitment to excellence, and that equips our trainees with exemplary skills and attitudes for a life's work in medicine.

We are committed to cultivating an inclusive, collaborative, and professional culture that respects individual differences, recognizes and rewards diverse talents, and helps each person reach their full potential.

The department is organized into the following 11 academic sections, each led by a section chief who reports to the chair. The section chiefs also lead their respective services at Yale New Haven Hospital and VA Connecticut Healthcare System.

The department traces its origins to the prominent early American physician Nathan Smith, who came to Yale in 1813 as one of the four founders of the medical school and lectured on the theory and practice of “physic,” as medical science was called at the time.
