Professor, Medicine and Epidemiology
Area of Interest
Dr. Ransohoff trained as one of the first clinical epidemiologists (at Yale, with Alvan Feinstein) and has written extensively on how to improve research methods used to evaluate diagnostic tests, with seminal publications in the New England Journal of Medicine (1978), Science (2003), Nature Reviews Cancer (2004, 2005), and other journals. As one of the first medical subspecialists (gastroenterology, trained at Univ. of Chicago) also trained in clinical epidemiology, he has written extensively about colon cancer screening regarding the use of colonoscopy, fecal occult blood testing, sigmoidoscopy, and, recently, new molecular tests. Fifteen years ago he extended his work to include molecular markers for cancer and has studied stool DNA testing and serum DNA testing for colon cancer. Working with the NCI’s Early Detection Research Network, he has also studied serum proteomics markers in colon neoplasia and in ovarian neoplasia. In training programs at UNC he has directed the Robert Wood Johnson Clinical Scholars Program and the NIH-funded K30 faculty development program, to train junior faculty to build careers in clinical and translational research.
