Which actress played Dr. Allison Cameron in House M.D.?

Jennifer Morrison played Dr. Allison Cameron in House M.D.

Cameron was one of the original members of House’s diagnostic team when the series began. She was an immunologist whose compassion and ethical concerns often contrasted with House’s blunt, highly pragmatic approach. Her medical perspective was especially valuable in cases involving immune-system disorders.

Morrison remained part of the main ensemble through several changes to the diagnostic department. Cameron also developed romantic feelings for House, later married Robert Chase, and experienced changing responsibilities at the hospital. These storylines made her more than a supporting diagnostician and gave the character a continuing role in the show’s interpersonal conflicts.

Jennifer Morrison later became widely recognized for playing Emma Swan in Once Upon a Time. That role is sometimes more familiar to international audiences, but Morrison’s earlier long television run included Cameron, one of House M.D.’s defining original doctors.
