In House M.D., what specialty does Dr. Lisa Cuddy primarily practice?

Dr. Lisa Cuddy primarily practices endocrinology in House M.D.

Cuddy is also the hospital administrator and, for much of the series, the dean of medicine at Princeton-Plainsboro Teaching Hospital. Her medical specialty is endocrinology, the branch of medicine concerned with hormones and glands such as the thyroid, pancreas, and adrenal glands.

Her administrative responsibilities frequently place her in conflict with House. She must manage budgets, legal risks, staffing, and patient safety while House pursues unusual diagnostic approaches. This gives Cuddy a role that is both medically credible and institutionally powerful. Her professional relationship with House is one of the show’s recurring sources of tension.

Cuddy is sometimes classified only by her executive position, which can obscure her original medical specialty. She is not primarily a neurologist or cardiologist. Lisa Edelstein played Cuddy, while Olivia Wilde played Remy “Thirteen” Hadley, another doctor whose specialty and story are often discussed alongside Cuddy’s in summaries of the series.
