About me

Reetu Mukherji, MD, is a fellowship-trained medical oncologist. She specializes in management of gastrointestinal malignancies, including esophagus, stomach, small bowel, colon, rectum, anal, pancreatic, and hepatobiliary cancers. Dr. Mukherji leads the medical oncology department’s clinical and research focus on upper gastrointestinal malignancies, including esophageal and gastric cancers.

She earned her medical degree from Temple University School of Medicine and completed her residency at Thomas Jefferson University Hospital, both of which are located in Philadelphia. Dr. Mukherji completed a fellowship in hematology/oncology at MedStar Georgetown University Hospital.

Dr. Mukherji has published in several peer-reviewed journals, including Current Treatment Options in Oncology and Journal of Clinical Oncology, on the role of immunotherapies, applications of prognostic genomic biomarkers, and applications of liquid biopsies in the management of patients with gastrointestinal malignancies. She has also designed investigator-initiated clinical trials studying emerging blood-based biomarkers like circulating tumor DNA and testing novel therapies across gastrointestinal cancers. Her research includes collaboration with basic scientists to study circulating tumor cells from liquid biopsies. 

She is a member of the American Society of Clinical Oncology, the American Society of Hematology, and the American Medical Association.
