Chris Taub (generally referred to as "Taub") is one of the three new teaching fellows hired by House in Season 4.

Taub was a successful plastic surgeon in a lucrative practice, but lost his ability to practice after he had an affair with a nurse that, in his words, "got real." His partners found out about the affair and used it to blackmail him, forcing him to sign a non-compete clause by threatening to tell his wife about the affair.

Despite betraying her, Taub was willing to give up his chosen practice completely, simply saying "I love my wife." He revealed a made up story about losing a patient to explain to his wife why he had to quit and gave her a four-carat diamond ring to make it up to her. In Wilson's Heart, after the death of Amber Volakis, he immediately climbed into bed fully dressed and hugged his wife tightly.

It is not certain why Taub sought out the fellowship position, but House believes that Taub is simply desperate and looking for any job to tide him over. He almost fired Taub in Ugly for directly going against his orders, but soon realized after digging into his background that Taub had risked his fellowship job with nothing else to fall back on. Intrigued by Taub's decisions, House decided to keep him.

In Don't Ever Change, Taub reveals that he is Jewish, though he describes himself as a non-practicing or a very liberal Reform one.
