What specialty does Lisa Cuddy lead as dean of medicine in House M.D.?

Lisa Cuddy leads endocrinology as dean of medicine in House M.D.

Cuddy, played by Lisa Edelstein, is the senior administrator who oversees Princeton-Plainsboro Teaching Hospital for much of the series. Her medical specialty is endocrinology, the study and treatment of hormones, glands, and related metabolic disorders.

The character’s administrative role creates an ongoing conflict with House. Cuddy recognizes his diagnostic brilliance but must also manage his rule-breaking, unauthorized treatments, and effect on hospital policy. Their professional tension eventually develops into a romantic relationship.

Because Cuddy is usually shown making executive decisions, viewers sometimes remember her primarily as a hospital administrator rather than as a physician. She is both: her background is in endocrinology, and the series establishes her as a medical doctor before and during her leadership at the hospital.
