Gastrointestinal Oncology, Medical Oncology


Mandar Deepak Muzumdar, MD, is a medical oncologist who specializes in gastrointestinal cancer, which is something that affected his life at a young age.

“My father passed away from duodenal (small intestine) cancer. This personal experience along with the exciting advances in cancer biology and cancer care over the last two decades drove me towards a career in oncology,” Dr. Muzumdar says.

In addition to clinical care, he researches pancreatic and lung cancers, and works with fellows, residents, interns, medical students, and graduate students.

“This work diversity allows me to make scientific discoveries and train the next generation of scientists and clinicians in hopes of making a greater impact on the care of patients with cancer,” Dr. Muzumdar says. “Having the opportunity to work with and give back to such diverse and amazing colleagues, trainees, and patients drives my work in research, education, and clinical care.”

Dr. Muzumdar’s laboratory explores the mechanisms by which genetic, environmental, and host factors contribute to cancer initiation, progression, and maintenance. The ultimate goal is to identify novel approaches for cancer prevention and treatment.
