Anne Dudek played Amber Volakis, a fellow competing for House's diagnostic team.
Volakis appears during the fourth season, when House dismisses his original team and conducts a competitive selection process to choose replacements. Her aggressive, strategic approach earns her the nickname “Cutthroat Bitch,” a label reflecting both her competitiveness and the team's hostility toward her.
Dudek's character became especially important after the selection storyline ended. Amber entered a relationship with Dr. James Wilson, creating tension with House and contributing to one of the show's major tragic arcs.
The role is sometimes confused with the actors who played House's later team members, including Olivia Wilde as Remy “Thirteen” Hadley. Anne Dudek is specifically associated with Amber Volakis.
