Dr. Chris Taub’s surname in House M.D. is Taub. Peter Jacobson played Taub, a plastic surgeon who joins House’s reworked diagnostic team in the fourth season.
Taub enters the series during House’s competitive hiring process, when House evaluates a large group of candidates before selecting a smaller team. His surgical experience and practical approach make him useful in difficult cases, while his personal life supplies several continuing storylines.
Unlike several colleagues, Taub is older and more established when he joins House’s team. The character’s complicated marriage and later family responsibilities distinguish him from the younger doctors competing for positions.
Taub is often confused with Lawrence Kutner, another doctor recruited during the same selection storyline, or with Chase, who belongs to the original team. Peter Jacobson’s character is Dr. Chris Taub, and the surname is the short canonical answer.
