Lisa Cuddy became dean of medicine at Princeton-Plainsboro in House M.D.
Lisa Cuddy is a fictional physician and hospital administrator portrayed by Lisa Edelstein. She serves as the dean of medicine and is one of Gregory House's most important professional counterparts. Cuddy frequently challenges House's behavior while also protecting his diagnostic abilities when she believes his work benefits patients.
Her administrative position places her above many of the doctors who appear in the series. She deals with hospital policy, budgets, staffing, legal exposure, and House's repeated breaches of rules. Her relationship with House develops beyond ordinary workplace conflict and becomes a major storyline in later seasons.
Cuddy is sometimes confused with Wilson, who is House's closest friend and head of oncology, or Foreman, who later takes an administrative leadership role. The question asks specifically about the dean of medicine, making Cuddy the unique answer. Edelstein played the character through the seventh season.
