What was the specialty of Lisa Cuddy, House M.D.’s hospital administrator?

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

Cuddy is the dean of medicine and hospital administrator at Princeton-Plainsboro Teaching Hospital. Although her administrative responsibilities dominate much of the series, the character is also established as an endocrinologist, a physician who treats disorders involving hormones and glands.

Her specialty creates an interesting contrast with House’s diagnostic medicine. Cuddy must manage budgets, staff, legal risks, and hospital policy while also understanding the medical work taking place in the institution. She frequently supports House’s department while imposing limits on his behavior and costly investigations.

Lisa Edelstein played Cuddy for much of the series. Cuddy’s professional relationship with House develops into a major personal storyline, but her role remains broader than that relationship: she is one of the hospital’s principal decision-makers and a physician with her own clinical background.
