Which fictional character was played by Anne Dudek in House M.D.?

Anne Dudek played Amber Volakis in House M.D.

Amber Volakis is a physician who competes for a place on House’s diagnostic team during the fourth season. Her aggressive, highly competitive approach earns her the nickname “Cutthroat Bitch,” a label used by House and the other doctors.

After leaving the selection process, Amber becomes romantically involved with James Wilson. She later suffers fatal injuries in a bus accident while traveling with House. The accident and its medical consequences form the central story of the two-part fifth-season finale, “House’s Head” and “Wilson’s Heart.”

Amber is sometimes confused with Remy Hadley, also known as Thirteen, who was played by Olivia Wilde, or Allison Cameron, played by Jennifer Morrison. Anne Dudek’s role was a recurring one, but Amber’s relationship with Wilson and her connection to House make her important to several major story arcs.
