In House M.D., Dr. Chase’s first name is Robert.
Robert Chase is an Australian intensivist and surgeon who begins the series as one of Gregory House’s original fellows. Jesse Spencer played Chase. His medical background, willingness to adapt, and sometimes cautious relationship with authority make him a distinctive member of the diagnostic team.
Chase is frequently called simply “Chase,” so viewers may overlook his given name. The character’s full name is Robert Chase, and his Australian background is part of his established biography rather than a detail inferred from the actor’s nationality.
Across the series, Chase develops from a junior doctor into a senior physician with greater independence. His career also connects him to surgery and intensive care, distinguishing him from Foreman’s neurology and Cameron’s immunology. Those specialties can help separate the original fellows when their surnames are used most often.
