In House M.D., which actress played Dr. Allison Cameron, an immunologist on House’s original team?

In House M.D., Jennifer Morrison played Dr. Allison Cameron, an immunologist on House’s original team.

Allison Cameron is one of the first three fellows recruited by Gregory House for the diagnostic department. Her specialty is immunology, and her strong concern for patients often contrasts with House’s deliberately detached and confrontational style.

Cameron’s personal and professional relationships are important in the early seasons. She works alongside Robert Chase and Eric Foreman, and her feelings about House create a continuing source of tension within the team.

Jennifer Morrison portrayed Cameron during the character’s main House M.D. run. Morrison later became known for roles including Emma Swan in Once Upon a Time, but Cameron remains one of her best-known early television characters.
