In House M.D., what specialty does Lisa Cuddy hold at Princeton-Plainsboro?

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

Lisa Cuddy is played by Lisa Edelstein and serves as the Dean of Medicine and hospital administrator at Princeton-Plainsboro Teaching Hospital. Although her administrative duties dominate much of the series, the character is an endocrinologist by training. Endocrinology focuses on hormones, glands, metabolism, and related disorders such as diabetes and thyroid disease.

Cuddy frequently supervises House, disputes his methods, and protects the hospital from the consequences of his behavior. Their professional arguments form a major recurring relationship in the series. Her authority comes from hospital leadership rather than from running the diagnostic department herself.

Viewers can confuse Cuddy’s specialty with the fields practiced by House’s team. Neurology, cardiology, and dermatology all appear in many hospital cases, but they are not Cuddy’s stated specialty. Her endocrinology background also connects her to the show’s broader interest in rare conditions involving hormones and metabolic systems.
