A board certified urologist, Dr. Dahm graduated from the University of Heidelberg in Germany before starting residency in general surgery and urology at Duke University in Durham, North Carolina. He subsequently completed an American Foundation for Urological Diseases (AFUD) fellowship at the same institution and earned a Masters degree in Health Sciences in Clinical Research from the Duke Clinical Research Institute. He was an Assistant Professor of Urology at Duke University Medical Center until 2006 when he moved to the University of Florida in Gainesville, where he held the rank of Associate Professor (2006-11) and Professor of Urology (2011-14). During the time, he also held the departmental positions of Director of Clinical Research (2006-14), Associate Residency Program Director (2006-2010) and Residency Program Director (2011-14).

Dr. Dahm is a fellow of the American College of Surgeons and an active member of the American Urologic Association. He has published more than 120 peer-reviewed articles and several book chapters. He is best known for his efforts to promote the principles of evidence-based medicine in urology through research and education. Dr. Dahm serves as the Coordinating Editor of the Cochrane Prostatic Diseases and Urological Cancers Group. He is also the urology lead of the IDEAL Collaboration that strives to improve how surgeons conduct clinical research as well as founding member of the US GRADE Network that promotes transparent methods for guideline development and clinical decision-making.
