In House M.D., Jennifer Morrison plays Dr. Allison Cameron.
Cameron is an immunologist and one of the three members of Gregory House's original diagnostic team, alongside Robert Chase and Eric Foreman. Her medical knowledge and strong concern for patients often lead her to question House's methods and the ethical consequences of his decisions.
Jennifer Morrison played Cameron from the series premiere and remained a major cast member during the show's early years. The character's story includes professional changes, complicated relationships with colleagues, and a continuing struggle to balance compassion with the demands of diagnostic medicine.
Cameron's surname is sometimes mixed up with Cuddy, another prominent female doctor in the series. Lisa Cuddy is the hospital's dean of medicine and an endocrinologist, whereas Allison Cameron begins as a fellow on House's diagnostic team and specializes in immunology.
