Lisa Cuddy is the hospital administrator who eventually becomes Dean of Medicine at Princeton-Plainsboro Teaching Hospital. She supervises House, manages his department, and repeatedly tries to balance his extraordinary diagnostic results against his rule-breaking behavior and treatment of colleagues.

The character was played by Lisa Edelstein. Cuddy and House have a long professional history, and their complicated relationship becomes a major storyline in the later seasons. Cuddy also has medical training and is shown making administrative and clinical decisions within the hospital.
