Ajay Maker


Surgical oncologist
Chief, Division of Surgical Oncology

Dr. Ajay V. Maker is a surgical oncologist and chief of the UCSF Division of Surgical Oncology. He is an expert in surgically treating complex gastrointestinal and hepatopancreatobiliary diseases (those affecting the liver, pancreas, gallbladder and bile ducts), as well as melanomas and sarcomas.

Maker's research aims to improve early detection of pancreas cancer and to develop new therapies for treating metastases (cancers that have spread from a primary site in the body). Under grants awarded by the Department of Defense and National Institutes of Health (NIH), he works on designing novel immunotherapies (treatments that harness the immune system to fight tumors), particularly for liver metastases from colon cancer.

Maker earned his medical degree at Yale School of Medicine. He completed a residency in general surgery at Brigham and Women's Hospital, an affiliate of Harvard Medical School. He trained in surgical oncology at the NIH and completed postdoctoral studies in tumor immunology at the National Cancer Institute; this research included working in trials that led to approval by the Food and Drug Administration of ipilimumab as a new treatment for metastatic melanoma. He later completed a fellowship in surgical oncology at Memorial Sloan Kettering Cancer Center and then gained experience in minimally invasive surgical techniques at the University of Paris. He came to UCSF from his hometown of Chicago, where he was a tenured professor of surgery and of microbiology and immunology at the University of Illinois at Chicago.

In 2015, Maker was the European Society of Surgical Oncology's international traveling fellow and was later honored with the Society of Surgical Oncology's Clinical Investigator Award. He has published more than 170 manuscripts, abstracts and book chapters, and he lectures all over the world. He serves on the editorial boards of many surgical and scientific journals; serves on NIH study sections, which evaluate the merit of proposed research; and has held leadership positions in numerous academic and scientific societies, including program chair of the Americas Hepato-Pancreato-Biliary Association and chair of the Society of Surgical Oncology's gastrointestinal working group. He is also active in various medical societies, including the Surgical Biology Club, Western Surgical Association, American Society of Clinical Oncology and Pancreas Club. He has been named numerous times to Castle Connolly's Top Doctors and Top Doctors for Cancer lists. He is a fellow of the American College of Surgeons and Society of Surgical Oncology.

    Please check with your health insurance plan regarding coverage for this type of care. Not all providers at UCSF are covered by every insurance plan.
