In House M.D., the surgeon on House's team is Robert Chase.
Chase is an Australian physician and one of the original members of House's diagnostic team. Jesse Spencer portrayed him. At the beginning of the series, Chase's surgical background distinguishes him from the team's internist and immunologist, and he often contributes practical procedural knowledge to difficult cases.
The character's professional path changes over time. After working under House, Chase develops greater independence and eventually becomes a leader in the diagnostic department. His relationships with Cameron and other colleagues also form important subplots.
Chase is easy to confuse with Eric Foreman, Allison Cameron, or Chris Taub, all of whom serve on House's teams at different points. Foreman is a neurologist, Cameron is an immunologist, and Taub is a plastic surgeon. The requested surname is Chase itself.
