Dr. Marshall Jacobs joined the faculty of the Department of Surgery at Johns Hopkins School of Medicine in May, 2013. Dr. Jacobs has been a cardiovascular surgeon and clinical investigator for three decades, with special emphasis on congenital heart disease. As Director of Pediatric Cardiac Surgery Outcomes Research at Johns Hopkins, he works with medical students, residents and fellows on clinical investigations and helps to coordinate data management, quality assessment, quality improvement initiatives and clinical trials related to the care of patients with congenital heart disease. 

Dr. Jacobs’ early investigative work focused on basic cardiovascular physiology, including myocardial response to pressure and volume overload under conditions of normal and abnormal coronary perfusion. He was the principle investigator of NIH-funded research that evaluated magnetic resonance imaging and spectroscopy in the diagnosis of cardiac transplant rejection in a primate model. He also created an intact animal model of Fontan circulation and explored various strategies for mechanical circulatory support of univentricular circulation. In the clinical realm he participated in the development and evaluation of innovations in the surgical management of congenital heart malformations, including the staged reconstructive approach to functionally univentricular hearts. 

His current concentration in outcomes research includes participation in the multi-institutional studies of the Congenital Heart Surgeons Society (CHSS). He served as Chair of the Research Committee and then as president of the CHSS (2014-2016). He has served as chair of the Society of Thoracic Surgeons Congenital Heart Surgery Database Task Force and the STS Congenital Heart Surgery Access and Publications Committee. The author of more than 300 peer reviewed publications, Dr. Jacobs is a member of several editorial boards and is the Founding Editor and past editor-in-chief of the World Journal for Pediatric and Congenital Heart Surgery. more
