What is the name of House's oncology colleague in House M.D.?

House's oncology colleague in House M.D. is James Wilson. Robert Sean Leonard played Wilson, who becomes Gregory House's closest and most enduring friend.

Wilson is the head of the oncology department at Princeton-Plainsboro Teaching Hospital. His medical specialty places him in frequent contact with patients facing serious illness, while his friendship with House gives the series a regular counterpoint to House's cynicism and isolation.

Wilson often challenges House's decisions, but he also enables some of House's most self-destructive behavior. Their relationship is complicated by arguments, reconciliations, practical jokes, and mutual loyalty. Wilson's calmer social style contrasts sharply with House's confrontational approach.

Eric Foreman and Robert Chase are members of House's diagnostic teams, not his oncology colleague. “James Cameron” is also a potential mix-up because Allison Cameron was an original team member; Wilson's first name is James, while Cameron's first name is Allison.
