Donna L. Farber is the Chief of Surgical Sciences, George H. Humphreys, II Professor of Surgical Sciences, and Professor of Microbiology and Immunology at Columbia University. Her research focuses on transplant immunology and memory T-cells. The Farber Lab is located in the Department of Microbiology and Immunology at Columbia University Irving Medical Center. Dr. Farber is in the Department of Surgery and the Department of Microbiology and Immunology at the Columbia University Vagelos College of Physicians and Surgeons. The lab's research is focused on defining how the immune system responds to pathogens and maintains homeostasis with age. We are particularly interested in understanding how the immune response is localized in tissue sites, and how T lymphocytes resident within tissues develop and maintain immunological memory to infection and vaccines.
