In House M.D., which original fellow is played by Jennifer Morrison?

Jennifer Morrison plays Allison Cameron, one of House’s original fellows, in House M.D.

Cameron is an immunologist whose medical knowledge contributes to House’s early diagnostic team. She is compassionate and strongly concerned with patients’ personal circumstances, qualities that often place her at odds with House’s detached and confrontational style.

Cameron’s history includes the loss of her husband, who died from thyroid cancer. That experience helps explain her emotional investment in patients and her interest in people facing serious disease. Her ethical instincts are a recurring source of disagreement within the team.

Morrison remained part of the series after the original team changed, although Cameron’s role and workplace relationships evolved. The character’s combination of medical ability and empathy made her a clear contrast to House and helped establish the moral debates that recur throughout the show.
