In House M.D., what specialty does Dr. Lisa Cuddy hold as a physician?

Dr. Lisa Cuddy’s medical specialty in House M.D. is endocrinology.

Cuddy, played by Lisa Edelstein, is the hospital administrator and Dean of Medicine for most of the series, but the character is also a physician trained in endocrinology. That specialty concerns hormones and the glands that produce them, including conditions involving the thyroid, adrenal glands, pancreas, and reproductive system.

Her administrative position means that viewers often remember Cuddy primarily as House’s supervisor rather than as a practicing specialist. She frequently balances hospital policy, patient safety, budgets, and House’s unconventional diagnostic methods. Her medical background helps explain why she can evaluate clinical arguments even when she is acting as an administrator.

Endocrinology should not be confused with neurology, Foreman’s specialty, or oncology, Wilson’s specialty. Cuddy’s professional authority comes from both her medical training and her leadership role at Princeton-Plainsboro.
