Advanced Transplant Hepatology Fellowship

The Section of Digestive Diseases offers a one-year fellowship in Transplant Hepatology. This program is accredited by the Accreditation Council for Graduate Medical Education (ACGME) and fulfills the requirement for the ABIM certifying examination in transplant hepatology. Our program offers the full range of training with exposure to adult and pediatric transplantation and living donor liver transplant performed at Yale New Haven Hospital.

All candidates must have completed an ACGME-credited fellowship in Gastroenterology at the time of starting the transplant fellowship.

Advanced Transplant Hepatology Fellowship Key Faculty

  • Fellowship Director; Professor of Medicine and Surgery Medical Director, Adult Liver Transplant

    Michael Schilsky, MD, became medical director of liver transplantation at Yale New Haven Hospital in 2007, with appointments in medicine and surgery at the Yale School of Medicine. Dr. Schilsky received his medical degree from the University of Chicago, Pritzker School of Medicine. He completed his residency and fellowship in gastroenterology and research training in liver diseases at Albert Einstein College of Medicine and Montefiore Medical Center. His clinical and research interests include transplant hepatology, inherited metabolic disorders of the liver, Wilson disease and hemochromatosis. Dr. Schilsky previously served as director of the liver medicine clinic at the Recanati/Miller Transplantation Institute at Mount Sinai Medical Center and medical director for liver transplantation at the New York Weill Cornell Medical Center, where he developed a comprehensive program for the care and evaluation of liver transplant patients. Dr. Schilsky coauthored the AASLD practice guidelines for Wilson disease and is author of numerous original manuscripts and reviews.

  • Ramesh Batra, MD, is the surgical director of liver transplant program at Yale Transplant Center. He is also a living donor liver surgeon for the transplant center besides being a multiorgan transplant surgeon for adult and pediatric patients. Alongside his transplant roles, he also performs complex hepatobiliary operations for liver tumors and biliary tract disorders in high risk patients.

    Dr. Batra's expertise is in living organ donation and also in transplanting extended spectrum aka “marginal” organs, both liver and kidneys for early transplant and reducing the time on organ transplant waiting list. With this ability, he continually seeks to find “opportunity” in organs declined by other transplant centers for his patients. Aside from maximizing utility and reducing organ discard, he is passionate about alleviating the ethical barriers in organ donation and transplantation. As a qualified and trained ethicist, he is nationally acclaimed in the field and constantly seeks to push the boundaries in organ transplant

    Dr. Batra in the early foundational years underwent the British system of surgical training in NHS based hospitals in United Kingdom, and was subsequently admitted to the Membership and Fellowship of The Royal College of Surgeons. He also completed the ASTS (American Society of Transplant Surgeons) abdominal transplant fellowship at the Mayo Clinic in liver, kidney and pancreas transplants along with pediatric liver transplants at Phoenix Children's hospital. 

    He is an active member of the American Society of Transplant Surgeons, American Society for Bioethics and Humanities, and also a Fellow of the American College of Surgeons. He currently serves on various national and international transplant and ethics committees along-with being on various editorial boards for medical and surgical journals to be at the forefront of transplant innovation.

  • Dr. Caldwell graduated from Bates College in Maine and the University of Pittsburgh School of Medicine. He trained in Internal Medicine at Yale-New Haven Hospital, following which he completed a Fellowship in Gastroenterology and Liver Disease at the University of Michigan Medical Center, focusing in Transplant Hepatology and becoming UNOS (United Network Organ Sharing) certified. Thereafter he was a member of the full time faculty in the Gastroenterology Division at Barnes Hospital and Washington University School of Medicine, where he later became co-director of Transplant Hepatology at Barnes. In 1998 he returned to New Haven and joined the clinical faculty of Yale New Haven Transplant Center (YNHTC) with an appointment as Clinical Associate Professor of Medicine at Yale School of Medicine.

    A full time clinician, Dr. Caldwell also mentors trainees in Internal Medicine and Gastroenterology and he is a recipient of the Vincent Deluca Award for Outstanding Teacher of Gastroenterology Fellows at Yale School of Medicine.

    Dr. Caldwell is board certified in both Gastroenterology (ABIM recertified 2015) and Transplant Hepatology (ABIM recertified 2018).  A member of the ACG (American College of Gastroenterology), AASLD (American Association for the Study of Liver Disease), and AST (American Society of Transplant), he serves on numerous committees including the Connecticut chapter of ALF (American Liver Foundation) and the organization Donate Life.

  • Dr. Jakab is a graduate of the Timisoara University of Medicine in Romania. Her internship and residency in Internal Medicine, as well as her gastroenterology fellowship training were completed at Norwalk Hospital, Norwalk, CT, programs affiliated with Yale University. She did elective rotations at the Center for Liver Disease and Transplantation, Columbia-Presbyterian Hospital, and the Department of Liver Transplantation and Hepatobiliary Surgery, Lahey Clinic. She received advanced training in Hepatology and Liver Transplantation at Thomas Jefferson University Hospital/Jefferson Medical College.

  • David C. Mulligan, MD, is an abdominal organ transplant surgeon performing both living and deceased donor liver, kidney, and pancreas transplants.

    He currently serves as Professor and Chair of Transplantation and Immunology in the Department of Surgery at Yale School of Medicine/Yale New Haven Health System.

    His clinical and academic focus surrounds living donor liver transplantation, expanding donation, and working on ways to utilize ex-vivo organ perfusion systems to increase transplantation in the United States.

    Dr. Mulligan and his team are testing novel strategies in immunosuppression; improved biomechanical organ preservation methods to reduce ischemia/reperfusion injury and promote regeneration; and working in the field of 3D bioprinting to collaborate in finding ways to grow new organs from stem cell precursors.

    He has performed more than 250 living donor transplants and has authored more that 180 publications. He also has served on numerous editorial review boards and presented across the U.S. and internationally.

    Dr. Mulligan’s leadership in solid organ transplantation across national and international platforms has grown considerably and he now serves as Immediate Past President of the United Network of Organ Sharing (UNOS)/Organ Procurement Transplant Network (OPTN), Member at-large on the Governing Board of the American Association for the Study of Liver Diseases, Past Chair of the Advisory Council on Transplantation (ACOT) to the Secretary of HHS, special government employee for FDA Medical Device Advisory Committee and chair of the Business Practice Committee of the American Society of Transplant Surgeons. He also contributes to the oversight and recommendations regarding the impacts of COVID-19 on solid organ transplantation in the U.S. for both the AASLD and the ASTS.

    In these visionary roles, he has led major changes in organ allocation and distribution and will hopefully culminate in substantial increases in organ transplants. Passionate about patient-centered care and building more resilient teams, he makes time to share his enjoyment of spending time in nature, especially near the ocean, with his wife and three children.
