Which character did Lisa Edelstein portray in House M.D.?

Lisa Edelstein portrayed Dr. Lisa Cuddy in House M.D. Cuddy is the hospital's dean of medicine and the administrator responsible for managing Gregory House's department and behavior.

Cuddy frequently challenges House over his methods, rule-breaking, and treatment decisions, while also recognizing his unusual diagnostic ability. Her administrative role places her between the hospital's legal and financial demands and House's insistence on clinical independence. The character therefore serves as both an authority figure and one of House's most important personal relationships.

Edelstein played Cuddy from the first season through the seventh season. She did not appear as a regular cast member in the eighth and final season. Her character is sometimes confused with House's fellows, but Cuddy is an administrator and physician rather than a member of the diagnostic team.
