Leadership


Program Director


Associate Program Director


MGB Division Chief, Gastroenterology, Hepatology & Endoscopy

Dr. David E. Cohen was the Division Chief at BWH from 2021 to 2025. This was an exciting period of growth, with expansion of clinical, research, and educational programs, along with the opening of a newly renovated, state-of-the art endoscopy center and the opening of additional facilities at Brigham and Women's Faulkner Hospital. Strengthened partnerships with the other divisions within the Department of Medicine and with hospital administration have improved digestive care and patient access across the institution. Dr. Cohen is an accomplished physician-scientist who mentored many students, fellows, and faculty at HMS and BWH. He was recruited to become the Chair of the Department of Medicine at Cedars-Sinai Medical Center in Los Angeles.

This is an exciting time at Massachusetts General Hospital (MGH) and 天美传媒l (BWH) as we start the process of integrating our divisions as a combined Mass General Brigham (MGB) Division of Gastroenterology, Hepatology & Endoscopy. Dr. Raymond Chung has been named the inaugural Division Chief of the combined MGB Division and starts in this role in August 2025.

Dr. Chung is Professor of Medicine at Harvard Medical School and holds the Zhou Family Endowed Chair in Gastroenterology. As a highly esteemed clinician and program builder, an NIH-funded physician-scientist, and a sought-after educator and mentor, Dr. Chung understands the opportunities, challenges, and complexities of our organization. Dr. Chung’s vision for the integrated Mass General Brigham Division includes leveraging the exceptional talent at BWH and MGH to develop an enhanced network of integrated GI services for the larger community; optimizing clinical operations to meet the needs of our patients and providers; building a culture of collaboration both within the Division and beyond; integrating the GI research mission across MGB and across disciplines; and most importantly for our trainees - safeguarding the training and development of the next generation of physicians and physician-scientists, without whom MGB would not have its world class reputation.

We will engage in the process of developing an integrated and enhanced MGB GI fellowship program over the next few years, capitalizing on the unique educational opportunities in all MGB sites. In the interim, our MGH and BWH GI fellowships will remain separate. However, with a combined MGB Division, our trainees will have full access to the diverse clinical, research, and educational opportunities across the MGB system.

Program Information and Current Fellows

Gastroenterology and Hepatology Fellowship Training Program

Fellowship Training Program Information

During the first year of training, the emphasis is on clinical gastroenterology and hepatology in the broadest sense with a focus on inpatient care. The year includes rotations on the consult services at 天美传媒l, Brigham and Women's Faulkner Hospital, and the VA Boston Healthcare System. There are 64 clinical and research faculty members at the 天美传媒l and Brigham and Women's Faulkner Hospital, and 10 at the Veterans Administration hospitals. At all the clinical sites, fellows work closely with experienced faculty to learn about gastroenterology, hepatology, and endoscopy. Consulting rounds are made on a daily basis with the gastroenterology faculty who provide patient care and education.

The program provides the majority of clinical training during the first year to allow fellows to focus on academic pursuits during the second and third year of fellowship (see additional information about the tracks below). However, fellows continue to receive clinical training in the outpatient setting and in endoscopy.

Each trainee sees patients in a weekly outpatient continuity clinic for all three years. During the second and third year they have a weekly endoscopy sessions during which they refine their skills in diagnostic and therapeutic endoscopy. Subspecialty experiences in a broad range of areas are also available, including inflammatory bowel disease (at the Crohn's and Colitis Center), hepatology, transplant hepatology (inpatient at MGH), pancreas, motility, and GI oncology (Dana-Farber Cancer Institute).

An advanced endoscopy service comprised of attendings and an advanced endoscopy fellow provides services in ERCP, EUS, and additional advanced procedures including bariatric endoscopy. Fellows receive broad exposure to inpatient and outpatient hepatology, including hepatology clinical and the hepatology consult service at 天美传媒l.

The hepatology section includes 6 board certified transplant hepatologists who actively see patients at 天美传媒l as well as the Mass General Brigham liver transplant program. There is a transplant clinic at BWH and fellows can rotate on the inpatient transplant hepatology service at Massachusetts General Hospital.

Formal conferences include a weekly didactic conference Grand Rounds, a clinical case conference every other week (Combined Longwood Conference) involving the three teaching institutions of the Harvard Medical School area (BWH, Beth Israel-Deaconess Medical Center, and Boston Children’s Hospital), clinical research conference, journal club, endoscopy conference (including quality assurance), liver histopathology conference, radiology/pathology conference, and multidisciplinary conferences focused on inflammatory bowel disease, motility, and pancreatic disease.

In addition, there are research seminars held through with the Harvard Digestive Diseases Center as well as the Brigham and Women's and Harvard Medical School communities that fellows can attend. The Division also has visiting scientist and mentorship programs. Importantly, our trainees play a major role in the teaching of residents and Harvard medical students at the hospitals through which they rotate.

Basic Science Research Track

The Basic Science Research Track fellowship is designed specifically for fellows who desire a career in basic laboratory research and are prepared to make a major commitment to basic scientific research.

During the second and third years of the Basic Research Track, which may be funded through our NIH Institutional Gastroenterology Training Program, the emphasis is on rigorous scientific training in laboratory research. Fellows have limited clinical responsibilities comprised of a weekly continuity clinic and endoscopy session and approximately three-five weeks per year on the inpatient consult service. Trainees are expected to initiate, organize and conduct their own experiments in the laboratory under the guidance and close supervision of a preceptor within the Division or the Harvard Medical Area.

Because of the proximity to, and close ties with, the basic science departments at Harvard Medical School and the Massachusetts Institute of Technology, trainees will have the opportunity to develop projects and to receive training in a variety of basic disciplines, utilizing molecular and cell biological, biochemical, physiological, biophysical, physical-chemical or immunological techniques.

The 天美传媒l, together with the Harvard Medical School, Children's Hospital Boston and Beth Israel-Deaconess Hospital, has been designated as a Digestive Diseases Center by NIH and is the recipient of a Digestive Diseases Center Award. This Center facilitates close interaction and collaboration among investigators with interests in the digestive and hepatic-pancreatico-biliary systems in these institutions.

Formal research training includes the Models of Disease Bootcamp which fellows often participate in the summer after first year, as well as other courses at Harvard Catalyst.

Research interests of the faculty at 天美传媒l and the VA Boston HealthCare System vary widely but all of the laboratories share equipment and expertise and interact closely in a collegial atmosphere. The Division also has been designated as a Center for Autoimmunity, which, together with the Dermatology and Neurology divisions, is funded to study autoimmune diseases such as Inflammatory Bowel Disease.

During the first two months of the second year, fellows can take the summer Program in Clinical Effectiveness at the Harvard School of Public Health. The curriculum includes required courses in biostatistics and epidemiology, as well as electives such as decision analysis and large database research. For the remainder of the year it is expected that fellows will work with a mentor, develop and execute projects in clinical research, and apply for research funding.

The third year is devoted to ongoing clinical research under the supervision of their mentor. In addition, it is possible for some fellows to take additional courses and obtain a Master’s degree in Public Health through an internal application and selection process. Clinical & Translational Sciences trainees participate in brief inpatient clinical rotations during the second and third year, as well as their weekly continuity clinic and endoscopy sessions.
