In House M.D., the surgeon on House’s original diagnostic team is Dr. Robert Chase.
Robert Chase is one of House’s first three fellows, along with Allison Cameron and Eric Foreman. Jesse Spencer plays Chase, who is initially identified with intensive care medicine and later develops a prominent career in surgery. His Australian background is an important part of his characterization and distinguishes him from his American colleagues.
Chase’s place on the team changes as the series progresses. He begins as a junior doctor selected by House, but he gradually gains confidence, technical authority, and independence. His relationship with House combines admiration, rivalry, and resentment as Chase’s own medical judgment develops.
The surname Chase is especially useful for separating him from Cameron and Foreman, the other original fellows. It is also distinct from Chris Taub and Lawrence Kutner, who join a later version of House’s team. The character should not be confused with actor Jesse Spencer, whose real name does not match Chase’s.
