Biography

Dr. Lennerz is board certified by the American Board of Pathology and the American Board of Medical Genetics. He joined the Massachusetts General Hospital Department of Pathology and Center for Integrated Diagnostics as a staff pathologist  in 2014, and is an assistant professor at Harvard Medical School. Dr. Lennerz trained as a pathologist assistant in Berlin, Germany in 1994 and studied both medicine and molecular medicine at the University of Erlangen, Germany where he also received his MD and PhD. He completed his residency training in anatomic pathology in 2008, and a fellowship in molecular genetic pathology in 2009 at Washington University in St. Louis, MO. After completing a two-year gastrointestinal and liver pathology fellowship at Massachusetts General Hospital in 2011, he led a research group on biomarkers in lymphoma at Ulm University, Germany. His interests are tissue-based biomarkers, and financial sustainability of molecular genetic diagnostics. . Early in 2015 Dr. Lennerz joined the Cancer Center's physician staff at Mass General, and began presenting at the Cancer Center Grand Rounds.
