Which character is the head of Diagnostic Medicine in House M.D.?

Gregory House is the head of Diagnostic Medicine in House M.D.

House, played by Hugh Laurie, leads a small team that investigates patients whose symptoms have resisted ordinary diagnosis. The department’s work is the engine of the series: each case requires House and his colleagues to compare clues, challenge assumptions, and revise theories.

House is a physician specializing in diagnostic medicine, with board certifications in infectious disease and nephrology in the show’s backstory. His expertise is paired with severe leg pain and dependence on the painkiller Vicodin, which affect his behavior and relationships.

The department’s membership changes several times. Eric Foreman, Robert Chase, and Allison Cameron form the original core team, while later seasons introduce physicians including Chris Taub, Lawrence Kutner, and Remy Hadley. House remains the department’s defining leader throughout the series.
