I see patients at


As a surgeon, Dr. Eil cares for patients with cancer involving of the liver, bile ducts (cholangiocarcinoma) and pancreas. As a scientist, Dr. Eil studies immunotherapy for these types of cancer. Immunotherapy supports the body’s natural immune response to cancer. Dr. Eil worked for three years at the National Cancer Institute. While there, he made discoveries about how immune cells fight cancer. This research is helping scientists understand and treat cancer. 

Following completion of his clinical fellowship in surgical oncology at Memorial Sloan Kettering Cancer Center, Dr. Eil was recruited back to OHSU to establish his research group. Dr. Eil continues to investigate the immune microenvironment and engineering T-cells to function within the context of cancers involving the liver and pancreas. His multidisciplinary expertise provides a unique perspective to reinvigorate T-cell function, ultimately improving the lives and outcomes of patients suffering from this disease.

Dr. Eil and his wife have two young children. They enjoy traveling and spending time outside as a family.
