What is the name of House’s first diagnostic team member played by Jennifer Morrison?

Jennifer Morrison played Allison Cameron, one of House’s original diagnostic team members.

Cameron joins Gregory House’s initial team at Princeton-Plainsboro alongside Robert Chase and Eric Foreman. She is an immunologist by training and is known for her strong empathy toward patients, which often contrasts with House’s more detached approach. Her personal and professional disagreements with House become recurring elements of the early seasons.

Cameron’s character is sometimes confused with later female doctors on House’s teams. Amber Volakis was a later applicant and team member, Remy “Thirteen” Hadley joined during the replacement-team period, and Martha Masters appeared near the end of the series. None of those characters is played by Morrison.

Morrison remained associated with the role through multiple stages of Cameron’s relationship with the hospital and the diagnostic department. The character’s medical background and ethical outlook helped establish the original team’s contrasting personalities.
