Dr. Chris Taub joined House's elite team during the show's fourth season.
Taub was a successful plastic surgeon before coming to Princeton Plainsboro. However, he lost his ability to practice after he had an affair with a nurse.
Taub is a stubbon individual, which enables him to stand up to House when needed. Near the end of season five, the economy began to affect Taub, as his financial portfolio isn't very strong these days.
