In House M.D., which specialist leads the hospital’s oncology department?

James Wilson leads the oncology department in House M.D.

Dr. James Evan Wilson is the head of oncology at Princeton-Plainsboro Teaching Hospital. He treats patients with cancer and is also Gregory House’s closest friend. Their friendship provides one of the show’s most consistent relationships across all eight seasons.

Wilson’s specialty distinguishes him from House. House heads Diagnostic Medicine and investigates unexplained illnesses, while Wilson focuses on cancers and the care of oncology patients. Wilson often brings a more empathetic and patient-centered approach to medical and personal problems.

Robert Sean Leonard played Wilson. The character’s full name is James Evan Wilson, but the short answer “James Wilson” is the standard name used throughout the series. Wilson’s oncology role is sometimes confused with Lisa Cuddy’s endocrinology specialty or House’s diagnostic work.
