Renowned surgical oncologist, researcher, leader, and strategist Ronald J. Weigel, MD, PhD, MBA, FACS, is the new Medical Director for ACS Cancer Programs. He succeeds Heidi Nelson, MD, FACS, who retired in August after serving admirably for 5 years in that position.
Dr. Weigel is the E. A. Crowell Jr. Professor and chair of the Department of Surgery with the University of Iowa Health Care in Iowa City. He also is a prolific researcher whose lab has focused on determining the mechanisms of hormone response in breast cancer, as well as identifying transcriptional mechanisms regulating patterns of gene expression in breast and colon cancer.
