Which original House M.D. team member specializes in immunology?

Allison Cameron is the original House M.D. team member who specializes in immunology. Jennifer Morrison played Cameron, one of the three doctors recruited for House’s first diagnostic team.

Cameron’s immunology background is particularly useful in cases involving autoimmune disease, abnormal immune responses, and unexplained inflammation. She is also portrayed as the most openly compassionate member of the early team, although she becomes more willing to challenge House as the series progresses.

The show’s later seasons introduced other female doctors whose specialties can cause confusion. Remy “Thirteen” Hadley, played by Olivia Wilde, is an internist with a background in internal medicine, while Martha Masters, played by Amber Tamblyn, is a medical student with a strong academic record.

Cameron was part of the original trio alongside neurologist Eric Foreman and intensivist Robert Chase. Her specialty, actress, and position on the first team are separate facts that are often blended together in casual summaries.
