Which character became House M.D.'s hospital dean of medicine?

Lisa Cuddy became the hospital dean of medicine in House M.D. She is the senior administrator at Princeton-Plainsboro Teaching Hospital and one of the people responsible for managing House.

Lisa Edelstein played Cuddy from the pilot through the end of season seven. Cuddy is an endocrinologist by training, but her administrative role requires her to balance hospital finances, patient safety, staff disagreements, and House's unconventional diagnostic methods.

Her professional relationship with House develops into a romantic relationship during season seven, creating additional tension between medical supervision and personal attachment. Cuddy is sometimes described simply as the hospital's “boss,” but her specific senior title is dean of medicine. She is also distinct from Wilson, who is an oncologist and House's friend rather than the hospital's chief administrator.
