He comes to this role from Massachusetts General Hospital (MGH), where he currently serves as vice chair of faculty affairs in the department of surgery and the John Homans professor of surgery at Harvard Medical School.

In this role, Mullen will be responsible for the overall operational leadership and strategic direction of the department of surgery, including the delivery of high-quality, patient-centered clinical care across all surgical service lines, as well as research and medical education. Through his leadership position within Geisel, he will oversee faculty development and mentoring and champion research programs within the department.

Mullen will also be nominated for appointment to the William N. and Bessie Allyn professor in surgery at the Geisel School of Medicine at Dartmouth. 

He is a surgical oncologist who is nationally and internationally recognized as an expert in the surgical treatment of upper gastrointestinal cancers and soft tissue and retroperitoneal sarcomas. He has been successful in conducting a wide range of investigation, from clinical to translational to surgical education research, and has received funding from the National Institutes of Health and private foundations. 

With extensive leadership experience in the field of surgery, Mullen previously served as the program director of the general surgery residency at MGH for nearly 14 years and currently serves as vice chair of faculty affairs and co-chair of the executive compensation committee in the department of surgery at MGH. He also serves as a member of the Mass General Brigham department of surgery integration task force. On a national level, Mullen is the current president of the Halsted Society.

Mullen has demonstrated a deep commitment to the education and training of the next generation of surgeons. He has been an active member of national committees in developing curricula, assessment tools, and innovative training paradigms for general surgery trainees. Mullen also served as chair of the training committee for the Society of Surgical Oncology, charged with the oversight of more than 60 breast surgical oncology fellowship programs in the United States, as well as a variety of educational and mentorship offerings. 

Mullen has received three prestigious awards in recognition of his accomplishments as a surgical educator, including the 2011 and 2022 Faculty Teaching Awards in the Department of Surgery at MGH and the 2014 Partners Program Director of the Year Award. He has also been an associate examiner for the American Board of Surgery Certifying Board Examination Committee since 2014.

Receiving his medical degree from the University of California, Davis School of Medicine, Mullen then completed his general surgery residency and a postdoctoral research fellowship at the MGH, followed by a fellowship in surgical oncology at the University of Texas M.D. Anderson Cancer Center.
