Lisa Cuddy is House M.D.'s hospital administrator and former medical-school dean.
Cuddy oversees Princeton-Plainsboro Teaching Hospital and repeatedly has to balance House's extraordinary diagnostic success against his rule-breaking, drug dependence, and disregard for hospital policy. Her authority makes her one of the few people able to impose consequences on him, although she often protects his department because of its value to patients.
The character is played by Lisa Edelstein. Cuddy and House have a long professional history, and the series eventually develops their relationship into a romantic storyline. Her responsibilities also include managing budgets, staffing, legal risks, and the wider institution beyond House's diagnostic team.
Stacy Warner is another important woman from House's past, while Allison Cameron and Amber Volakis are doctors who work with him. Those names are therefore plausible mix-ups, but Lisa Cuddy is the hospital administrator associated with the role.
