Noam Jacob, MD, earned his bachelor's degree in philosophy and molecular biology from University of California, Berkeley. He then investigated genetic deletion or overexpression of cytokines central to T cell, B cell and innate immune cell function in autoimmunity at University of Southern California (USC), prior to obtaining his medical degree from the Keck School of Medicine at USC. He completed specialty training in internal medicine at Mount Sinai Medical Center, New York. He is now pursuing subspecialty training in gastroenterology with a research focus on intestinal fibrosis in inflammatory bowel disease.
