In House M.D., the hospital administrator who becomes Dean of Medicine is Dr. Lisa Cuddy.
Lisa Cuddy is portrayed by Lisa Edelstein and serves as one of House’s principal professional foils. She is responsible for managing the hospital while also trying to preserve House’s diagnostic work, control his rule-breaking behavior, and protect the institution from legal and financial risks.
Cuddy’s authority changes during the series. She is initially the hospital’s administrator and later holds the title of Dean of Medicine. Her relationship with House includes professional conflict, mutual respect, and a short-lived romantic relationship, making her role broader than that of a conventional supervisor.
The character is sometimes confused with the members of House’s diagnostic teams, such as Cameron, Foreman, or Thirteen. Cuddy is an administrator and endocrinologist rather than one of House’s regular fellows. Her position gives the series an ongoing perspective on how House’s methods affect the wider hospital.
