Björn Dirk Krapohl (born 26 January 1965, Kettiwg, Germany) is a German surgeon, specializing in plastic surgery and hand surgery at the University of Lübeck and the Charité in Berlin. He is known for his work in the fields of reconstructive microsurgery, hand surgery, and breast surgery. Biography. Krapohl studied human medicine at the universities of Giessen, Aachen, Paris, London (Canada), Toronto (Canada), Philadelphia and Cologne. In 1995 he was promoted to doctor of medicine at the University of Cologne and also finished the United States Medical Licensing Examination (ECFMG licence), Philadelphia, USA. He hold several positions  till 2003 including medicine at The Cleveland Clinic Foundation, Cleveland, USA and at the Section of Telerobotics, Jet Propulsion Laboratory, NASA, Pasadena, USA. He obtained his licensure for plastic surgery in 2003 and was habilitated in the discipline of plastic surgery at the University of Lübeck in the same year. He also obtained a venia docendi at the University of Vienna. In 2005 he obtained an additional title for hand surgery. Krapohl was named head of the Department of Plastic Surgery and Hand Surgery at the Armed Forces Hospital (Bundwehrkrankenhaus) Berlin and consulting physician at the Center of Musculoskeletal Surgery  at the Charité, University Medicine. He was named lecturer of the Charité at the Armed Forces Hospital Berlin and at the lecturer-association of the Charité in 2007. The University of Lübeck appointed Krapohl as associate professor in 2008.

Scientific contribution. Since the beginning of his university career, Krapohl has focused on microsurgery of peripheral nerves and vessels. While working at the Cleveland Clinic Krapohl was  involved in the development of animal models for transplantation of extremities and organs. Furthermore, he established animal models for microvascular thrombosis and thrombolysis. In 1997 the NASA Jet Propulsion Laboratory recruited Krapohl for the development of a prototype robot for microsurgical procedures in collaboration with the NASA engineers. Later on he continued his interest in microsurgery and especially in microsurgical replantation of extremities. When he began his work at the Military Hospital in Berlin he gradually focused on surgery of the breast. He prove that in military guards just the impact of the carbine to the chest while exercising can  induce unilateral breast growth. Thereby he verified a new etiology of male gynecomastia due to mechanical stimulation. His findings were integrated into the guidelines of gynecomastia.
