About Haley Ellis, MD
Dr. Ellis is a medical oncologist at Massachusetts General Hospital and Instructor in Medicine at Harvard Medical School. Her clinical practice involves caring for patients at the Tucker Gosnell Center for Gastrointestinal Cancers and the Henri & Belinda Termeer Center for Targeted Therapies, where innovative early phase clinical trials are conducted.
Dr. Ellis' clinical and research interests are focused on biliary cancers (cholangiocarcinoma and gallbladder cancer). She is dedicated to advancing the understanding and treatments of these cancers through scientific research and clinical trials. During her training at Memorial Sloan Kettering Cancer Center, University College Dublin, and Washington University in St. Louis, she garnered numerous accolades in medicine and oncology, including a prestigious clinician-scientist research scholarship. Dr. Ellis subsequently completed a medical oncology fellowship at Dana-Farber Cancer Institute, Brigham and Women's Hospital, and Massachusetts General Hospital, where she was selected as chief fellow. She is a member of the American Association for Cancer Research (AACR), American Society of Clinical Oncology (ASCO), and International Cholangiocarcinoma Research Network (ICRN). In addition to collaborating with a multidisciplinary team, she also enjoys working with patient/research advocates to provide comprehensive and compassionate care to her patients.

Research
In addition to clinical care, Dr. Ellis is a translational researcher specializing in cholangiocarcinoma in Dr. Nabeel Bardeesy's laboratory at MGH. Since her fellowship training, she has actively contributed to patient-centered research, connecting clinical observations to scientific investigations through a bench-to-bedside and bedside-to-bench approach. In the lab, patient-derived models are used to understand the biology of cholangiocarcinoma, explore mechanisms of response and resistance to targeted therapies, and develop novel therapeutic strategies. Dr. Ellis has received a number of awards and grants supporting these research endeavors, including an ASCO Conquer Cancer Young Investigator Award. Her enthusiasm for clinical/translational research is driven by a deep commitment to improving outcomes for patients with cholangiocarcinoma.
