What was Gregory House’s job title at Princeton-Plainsboro in House M.D.?

Gregory House was the head of Diagnostic Medicine at Princeton-Plainsboro in House M.D.

The department handles cases that other physicians have been unable to diagnose. House leads a small team of fellows who investigate symptoms, review medical histories, order tests, and challenge one another’s theories. This unusual structure provides the show with its recurring diagnostic puzzle format.

House is a board-certified diagnostician with specialties in infectious disease and nephrology, but his hospital role is broader than either specialty alone. He applies knowledge from multiple medical fields to rare or unexplained illnesses. His job title therefore differs from titles such as chief of surgery or emergency-department director.

The department is fictionalized for dramatic purposes. Real hospitals may have diagnostic medicine services, but their organization and authority can differ substantially. House’s unusual independence, frequent rule-breaking, and control over difficult cases are storytelling devices rather than a universal model of hospital administration.
