Dr. Chris Taub is known for plastic surgery before joining House’s diagnostic team.
Taub enters the series during the team-rebuilding storyline in season four. Before working in diagnostic medicine, he had been a successful plastic surgeon. House recruits him because he combines surgical experience with practical medical reasoning, even though Taub’s past includes professional and personal complications.
The character is played by Peter Jacobson. Taub becomes one of the more durable members of House’s later diagnostic teams and remains involved in difficult cases, clinical disagreements, and the changing structure of the department. His surgical background gives him a perspective different from that of clinicians trained primarily in internal medicine or neurology.
Plastic surgery includes reconstructive procedures as well as cosmetic operations, so the specialty should not be reduced to cosmetic work alone. Taub’s earlier career is specifically identified as plastic surgery, making that the precise answer rather than the broader category of surgery.
