Yale School of Medicine

Yale School of Medicine educates future leaders in medicine and biomedical science. Since 1839, medical students have written a thesis based on original research, reflecting that the scientific process of investigation, observation, interpretation of data, and critical evaluation of literature are fundamental to the practice of medicine. A significant number are awarded fifth-year research fellowships and earn the Master of Health Science degree. Each year, approximately 20 students enroll in the school’s MD-PhD Program, one of the original Medical Scientist Training Programs established and funded by the National Institutes of Health (NIH). earn a PhD degree through the Faculty of Arts and Sciences. YSM residents, fellows, and faculty, as well as individuals from other institutions, can earn a two-year Master of Health Science degree. The Yale School of Medicine also offers joint degree programs with other professional schools, including Public Health, Law, Management, Engineering & Applied Science, and Divinity. YSM’s campus-based Physician Associate (PA) Program, one of the oldest PA programs in the country, trains students to become compassionate, high-quality, patient-centered PAs. Yale System The school employs the "Yale System" established by YSM Dean Milton Winternitz in the 1920s, wherein first- and second-year students are not graded or ranked among their classmates. In addition, course examinations are anonymous and are intended only for students' self-evaluation. Student performance is thus based on seminar participation, qualifying examinations (if a student fails, it is his/her responsibility to meet with a professor and arrange for an alternative assessment—passing grades are not released), clinical clerkship evaluations, and the United States Medical Licensing Examination (USMLE). Prior to graduation, students are required to submit a thesis based on original research. The school ranked third for NIH research funding in 2024 as reported by the Blue Ridge Institute for Medical Research. ==History==

at the corner of Grove and Prospect Streets. Originally leased by Yale, the building was later purchased with funds from the Connecticut State Legislature. In 18th-century United States, credentials were not needed to practice medicine. Prior to the founding of the medical school, Yale graduates would train through an apprenticeship to become physicians. Yale President Ezra Stiles conceived the idea of training physicians at Yale and ultimately, his successor Timothy Dwight IV helped found the medical school. The school was chartered in 1810 and opened in New Haven in 1813. Nathan Smith (medicine and surgery) and Benjamin Silliman (pharmacology) were the first faculty members. Silliman was a professor of chemistry and taught at both Yale College and the medical school. The other two founding faculty were Jonathan Knight, anatomy, physiology and surgery, and Eli Ives, pediatrics. One of Yale's earliest medical graduates was Dr. Asaph Leavitt Bissell of Hanover, New Hampshire, who graduated in 1815, a member of the school's second graduating class. Following his graduation, Dr. Bissell moved to Suffield, Connecticut, a tobacco-farming community where his parents had lived and where he practiced as a country physician for the rest of his life. The saddlebags that Dr. Bissell carried in his practice, packed with paper packets and glass bottles, are today in the school's Medical Historical Library. In 1916, a little more than a century after its founding, Yale School of Medicine admitted its first female students. At the time, this stood in marked contrast to the ethos of other institutions such as Harvard, which considered it “unladylike” for women to attend medical school at the time. The three women admitted to the Class of 1916 were exceptional—unlike their male counterparts, who needed only two years of college education, they were required to hold a college degree, and a quota further restricted the number of women who were admitted. Throughout its history, Yale School of Medicine faculty have been credited with seminal scientific discoveries. Pediatrician Martha May Eliot, MD, who was recruited to Yale by Edwards A. Park, MD, chair of the medical school’s first Department of Pediatrics, are together credited with developing a cure for rickets in 1925. Early in 1942, Louis S. Goodman, MD, and Alfred Gilman, PhD, assistant professors in Yale’s new Department of Pharmacology, began to study nitrogen mustard, an agent that was derived from a lethal gas used in the trenches of World War I. Building on research that had languished for years, the two young scientists found in a derivative of mustard gas the first effective chemotherapy for cancer. In 1998, Charles Janeway, MD, Yale Cancer Center immunologist, established and proved his theory of innate immunity. In the 1960s, Louis Gluck, MD, a member of the Department of Pediatrics faculty, created the first neonatal intensive care unit (NICU). In the late 1970s, William Tamborlane, MD, and the late Robert Sherwin, MD, transformed the treatment of type 1 diabetes by developing the insulin pump. Research led by Yale School of Medicine endocrinologist Kevan Herold, MD, resulted in the Food and Drug Administration's approval in 2022 of teplizumab (Tzield®), a medication that can delay the onset of type 1 diabetes—marking the first treatment to change the course of this autoimmune disease since the discovery of insulin in 1922. In the field of psychiatry, following pioneering research led by Yale School of Medicine psychiatrist John Krystal, MD, and his colleagues Dennis Charney, MD, and Ronald Duman, PhD, the Food and Drug Administration approved in 2019 a nasal spray called esketamine, derived from ketamine (an anesthetic with rapid-acting effect), for treatment-resistant depression. The original building (at Grove and Prospect) later became Sheffield Hall, part of the Sheffield Scientific School (razed in 1931). In 1860, the school moved to Medical Hall on York Street, near Chapel (this building was razed in 1957). In 1925, the school moved to its current campus, neighboring the hospital. This campus includes the Sterling Hall of Medicine (erected in 1925), Boyer Center for Molecular Medicine (1991, designed by Cesar Pelli), Anlyan Center (2003, designed by Payette Associates and Venturi Scott Brown) and the Amistad Building (2007, designed by Herbert Newman)). On March 28, 2022, Jamie Petrone-Codrington, a former administrator pled guilty to fraud and tax charges for the theft of over $40 million of computer and electronic software. Jamie Petrone-Codrington illegally bought and sold hardware purchased for the School of Medicine, starting in 2013. According to the court records, Petrone-Codrington was turned in by an anonymous tip after being seen loading computer equipment into her private vehicle, and after ordering high volumes of equipment. ==Clinical Affiliations==

from the south , York Street entrance, New Haven, CT. An affiliation agreement between the medical school and Grace-New Haven Community Hospital in 1965 created Yale New Haven Hospital (YNHH), which expanded in 1993 with the opening of the Children’s Hospital, and again in 2000 with the acquisition of the Psychiatric Hospital. In 1999, an affiliation agreement was established between the medical school and Yale New Haven Health System. The two institutions collaborate to provide clinical care, undergraduate and graduate medical education, and to facilitate clinical research. ==Deans==
