In House M.D., what specialty does Lisa Cuddy identify as her medical specialty?

In House M.D., Lisa Cuddy's medical specialty is endocrinology.

Dr. Lisa Cuddy is the dean of medicine and hospital administrator at Princeton-Plainsboro Teaching Hospital for most of the series. She is also a physician trained in endocrinology, the branch of medicine concerned with hormones, glands, and metabolic regulation. That background helps distinguish her medical expertise from House's diagnostic specialization.

Cuddy spends much of the show managing the institution rather than treating patients full time. She must balance budgets, legal obligations, staff discipline, and patient care, while frequently supervising or restraining House's unconventional decisions. Her administrative authority makes her one of the few people able to impose consequences on him.

Lisa Edelstein played Cuddy from the first season through the seventh season. The character's professional relationship with House gradually develops into a more personal storyline. Cuddy's endocrinology specialty is a stable biographical detail, while her exact administrative title and responsibilities evolve during the hospital's changing leadership.
