Which character is the chair of oncology at Princeton-Plainsboro in House, M.D.?

James Wilson is the chair of oncology at Princeton-Plainsboro in House, M.D.

Dr. James Evan Wilson is portrayed as Gregory House’s closest friend and a major recurring character. As an oncologist, Wilson treats patients with cancer and often provides House with a more empathetic counterpoint. His willingness to listen to patients and colleagues contrasts with House’s confrontational style, although Wilson also has personal flaws and difficult professional choices.

Robert Sean Leonard played Wilson throughout the series. The character’s friendship with House is one of the show’s central relationships, and Wilson frequently helps House despite disapproving of his behavior. Their bond becomes especially important in the final season when Wilson receives a terminal cancer diagnosis.

Wilson is sometimes mistaken for the hospital’s dean of medicine or for a member of House’s diagnostic team. Those are different roles. Lisa Cuddy holds the dean position for much of the series, while Wilson remains associated primarily with oncology and with House’s personal life.
