Charles H. Evans, Jr., M.D., Ph.D., is a professor and chair of the Department of Human Science at Georgetown University School of Nursing & Health Studies. A pediatrician and immunologist, Dr. Evans received his B.S. in biology from Union College (NY), and his M.D. and Ph.D. degrees from the University of Virginia. His advanced training in pediatrics was at the University of Virginia Medical Center. Following his postgraduate training he was appointed to the National Institutes of Health intramural staff as a principal investigator. From 1975-1998 as a physician scientist he served as Chief of the Tumor Biology Section at the National Cancer Institute and as a Captain in the U.S. Public Health Service Commissioned Officers Corps at the National Institutes of Health in Bethesda, MD. Dr. Evans research interests are carcinogenesis (the etiology of cancer), the normal immune system defenses to the development of cancer, and methodology in clinical trials with small numbers of participants, e.g. space medicine and astronaut healthcare, and mentoring in adolescence. While at NIH he discovered the ability of cytokines to directly prevent carcinogenesis and was the first to isolate a direct acting anticarcinogenic cytokine for which he was awarded four U.S. Patents.
