In House M.D., Dr. Lisa Cuddy’s medical specialty is endocrinology.
Cuddy is the dean of medicine and administrator at Princeton-Plainsboro Teaching Hospital for much of the series. Before and alongside her administrative career, she is identified as an endocrinologist, a physician who studies hormones and disorders involving glands such as the thyroid, pancreas, and adrenal glands.
Her specialty is an important contrast with House’s broad diagnostic role. Cuddy is responsible for hospital policy, budgets, staffing, and risk management, while House routinely pushes against institutional rules in pursuit of a diagnosis. Their professional arguments are a recurring source of conflict.
The character was played by Lisa Edelstein. Cuddy later becomes House’s supervisor and romantic partner, but her formal medical field remains endocrinology. She is not an oncologist; that is James Wilson’s specialty.
