The University of California, Davis (also referred to as UCD, UC Davis, or Davis), is a public research university and land-grant university as well as one of the 10 campuses of the University of California (UC) system. It is adjacent to Davis, California, west of Sacramento, and has the third-largest enrollment in the UC System after UCLA and UC Berkeley. The institution was founded as a branch in 1909 and became its own separate entity in 1959. It has been labeled one of the "Public Ivies", a publicly funded university considered to provide a quality of education comparable to those of the Ivy League. The Carnegie Foundation classifies UC Davis as a comprehensive doctoral research university with a medical program, and very high research activity. The UC Davis faculty includes 23 members of the National Academy of Sciences, 30 members of the American Academy of Arts and Sciences, 17 members of the American Law Institute, 14 members of the Institute of Medicine, and 14 members of the National Academy of Engineering. Among other honors, university faculty, alumni, and researchers have won the Nobel Peace Prize, Presidential Medal of Freedom, Pulitzer Prize, MacArthur Fellowship, National Medal of Science, Blue Planet Prize, and Presidential Early Career Award for Scientists and Engineers. Founded as primarily an agricultural campus, the university has expanded over the past century to include graduate and professional programs in medicine (which includes the UC Davis Medical Center), law, veterinary medicine, education, nursing, and business management, in addition to 90 research programs offered by UC Davis Graduate Studies. The UC Davis School of Veterinary Medicine is the largest in the United States and has been ranked first in the nation for two consecutive years, 2015 and 2016. The UC Davis Aggies athletic teams compete in the NCAA Division I level, primarily in the Big West Conference as well as the Big Sky Conference (football only) and the Mountain Pacific Sports Federation. In its first year of full Division I status, 11 UC Davis teams qualified for NCAA post-season competition.
