In House M.D., which fictional doctor leads the Department of Diagnostic Medicine?

In House M.D., Gregory House leads the Department of Diagnostic Medicine.

House heads a specialized team that investigates patients whose symptoms have resisted ordinary diagnosis. His methods rely on unusual hypotheses, repeated testing, and intense debate, while his abrasive manner frequently creates conflict with patients and colleagues.

The department is fictional, but it reflects the real medical field of internal medicine and the diagnostic process. House is described as a board-certified diagnostician with expertise in infectious disease and nephrology, though the series gives him an unusually broad scope of practice.

House’s title and department change in some storylines, particularly when hospital rules or his legal problems intervene. Nevertheless, the core premise of the series is built around him leading a diagnostic team at Princeton-Plainsboro Teaching Hospital.
