Dr. Schreiber is the Alumni Endowed Professor of Pathology and Immunology, Professor of Molecular Microbiology and Tumor Immunology Program Leader for the Siteman Comprehensive Cancer Center at Washington University School of Medicine and an Affiliate of the Ludwig Institute for Cancer Research. He is a Fellow of the American Association of Science, an Associate Director of the Cancer Research Institute, a member of the Board of Scientific Advisors for the National Cancer Institute, and a past president of the Society for Leukocyte Biology. His lab is highly regarded for its research on the molecular cell biology and immunology of interferon-gamma and its receptor, as well as its strong expertise in mAb discovery. Dr. Schreiber’s group unequivocally demonstrated that the immune system provides an extrinsic tumor suppressor function (cancer immunosurveillance) capable of eliminating spontaneous- and carcinogen-induced primary tumors.
