The UCLA-Affiliated Infectious Diseases fellowship is a multicampus, subspecialty training program in clinical infectious disease and related clinical and basic science research. The program utilizes the clinical and laboratory resources of the VA Greater Los Angeles Healthcare System, the Cedars-Sinai Medical Center, and the Los Angeles County Olive View-UCLA Medical Center. These three facilities have a combined occupancy of over 1200 beds and care for a very diverse patient population providing trainees with exceptional clinical experience. Fellows identify a faculty mentor and complete a research project by the end of the 2-year program. There are excellent research opportunities available through the program faculty as well as other researchers at UCLA. A third fellowship year can be arranged by outstanding trainees interested in pursuing additional research experience.
