What medical specialty does Lisa Cuddy hold in House M.D.?

Lisa Cuddy’s medical specialty in House M.D. is endocrinology. Cuddy is the hospital administrator and dean of medicine at Princeton-Plainsboro Teaching Hospital, and the series identifies her as an endocrinologist.

Endocrinology is the branch of medicine concerned with hormones and glands, including conditions involving diabetes, thyroid disorders, adrenal glands, and reproductive hormones. This specialty differs from neurology, cardiology, and oncology, which focus primarily on the nervous system, heart, and cancer.

Cuddy’s administrative position means the show usually presents her as House’s supervisor rather than as a practicing specialist handling every case. She frequently has to balance hospital policy, financial concerns, patient care, and House’s rule-breaking.

Lisa Edelstein played Cuddy for the first seven seasons. The character’s professional authority creates a continuing source of conflict with House, whose diagnostic successes do not exempt him from institutional rules.
