After leaving House M.D.’s diagnostic team, Dr. Robert Chase practices surgery.
Chase begins the series as one of House’s original fellows, but his career does not remain confined to diagnostic medicine. His professional background and later decisions lead him into surgical work before he eventually returns to the diagnostic department.
This career detail is easy to mix up with the specialties of other principal characters. Eric Foreman is associated with neurology, James Wilson leads oncology, and Gregory House heads diagnostic medicine. Chase’s changing role is part of his long character arc rather than a single unchanging specialty.
Jesse Spencer played Chase throughout the series. By the end of the show, Chase has become a more experienced physician and assumes leadership of the diagnostic department after House’s departure.
