In House M.D., what is the name of House’s friend who is head of oncology?

James Wilson is House M.D.’s friend and the head of oncology at Princeton-Plainsboro.

Dr. Wilson is portrayed as a skilled oncologist whose work involves diagnosing and treating cancer. His professional relationship with House is unusual: Wilson often acts as House’s confidant, moral counterweight, and occasional accomplice, even when he disapproves of House’s behavior. Their friendship gives the series a stable emotional center amid frequent staff changes.

Wilson’s personal life is a recurring story source. The show explores his marriages, family connections, and tendency to become deeply involved in other people’s problems. These details complicate the common impression that he is simply the gentle opposite of House; Wilson can also be secretive, impulsive, and capable of bending rules.

Robert Sean Leonard played Wilson for all eight seasons. The character’s first name is James, while House is usually identified by his surname. Lisa Cuddy, another major colleague, was the hospital’s dean of medicine for much of the series and is not the oncology chief.
