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

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

Cameron was one of Gregory House’s original diagnostic fellows and appeared from the pilot onward. The character was known for her empathy, ethical concern, and interest in treating patients as people rather than merely as medical puzzles. Morrison’s performance helped establish Cameron as an important member of House’s first diagnostic team.

The role is sometimes confused with those of Olivia Wilde, who played fellow physician Remy “Thirteen” Hadley, or Anne Dudek, who played Amber Volakis. Morrison remained associated with House M.D. for several seasons, although Cameron’s position and screen time changed as the hospital’s teams were reorganized. Outside the series, Morrison became widely known for playing Emma Swan in Once Upon a Time and also appeared in films including Star Trek.
