In House M.D., the doctor known as Dr. Chase has the surname Chase; his full name is Robert Chase.
Robert Chase is an Australian intensive-care specialist who joins House's original diagnostic team at Princeton-Plainsboro. Jesse Spencer played the character throughout the series. Chase initially appears as one of House's fellows and gradually develops greater confidence, independence, and authority as his career progresses.
Chase is part of the original trio that also includes Allison Cameron and Eric Foreman. Their differing personalities create an important early team dynamic: Cameron is strongly empathetic, Foreman is ambitious and skeptical, and Chase is often more pragmatic and politically aware. The trio's medical specialties and personal choices shape many of the show's early cases.
The character's surname is easy to confuse with “Foreman” because both remain associated with House's department over much of the series. Chase is the Australian doctor, while Foreman is played by Omar Epps.
