Ralph H. Hruban

Ralph H. Hruban, M.D.

Johns Hopkins University School of Medicine

Dr. Ralph Hruban attended the Johns Hopkins University School of Medicine. He did a residency in Anatomic Pathology at Hopkins, followed by a fellowship in Surgical Pathology at Memorial Sloan Kettering Cancer Center in New York. Dr. Hruban then returned to Hopkins where he rose through the ranks. He is now the Baxley Professor and Director of the Department of Pathology, and the Director of the Sol Goldman Pancreatic Cancer Research Center.

Dr. Hruban has devoted his academic career to the study of tumors of the pancreas. He has made significant contributions to our understanding of the genetic drivers of all types of pancreas tumors - ductal, acinar, cystic and neuroendocrine- and he helped translate these genetic discoveries to patient care. His work on Pancreatic Intraepithelial Neoplasia (PanIN) and Intraductal Papillary Mucinous Neoplasms (IPMNs), the precursor lesions that give rise to invasive pancreas cancer, has led to new approaches to the early detection of pancreatic neoplasia. He founded the National Familial Pancreas Tumor Registry (NFPTR), and helped define the clustering of pancreatic cancer in families as well as discover new familial pancreatic cancer genes (PALB2 and ATM). These discoveries now guide genetic counseling. Dr. Hruban has over 750 scientific papers, and authored or coauthored six books, including the ARP Fascicle on Tumors of the Pancreas and the World Health Organization's "blue book" on tumors of the digestive tract. Ralph is cited by the "Essential Science Indicators" as the most cited pancreas cancer scientist in the world, and has been recognized on multiple occassions as a Thomson Reuters Highly Cited Researcher. He was inducted into the German National Academy of Sciences Leopoldina. Selected awards include the Ramzi Cotran Award from the United States and Canadian Academy of Pathology; the Arthur Purdy Stout Prize from the Arthur Purdy Stout Society; the Fred Stewart Award; the Frank H. Netter Award for Special Contributions to Medical Education; the Ruth Leff Siegel Award for Excellence in Pancreatic Cancer Research; the Johns Hopkins University Distinguished Alumni Award; and five teaching awards from the School of Medicine, including the Educational Innovation Award. He received the Team Science Award from the American Association for Cancer Research in 2013 and in 2017. He was appointed to the Board of Directors of the United States and Canadian Academy of Pathology in 2017.
