What is the name of House M.D.'s head of Diagnostic Medicine?

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

House leads a small team that investigates puzzling cases referred to Princeton-Plainsboro Teaching Hospital. His specialty is not a standard organ-based field such as cardiology or neurology; instead, he applies broad medical knowledge and diagnostic reasoning to patients whose illnesses remain unexplained.

The character was created by David Shore and played by Hugh Laurie. House is known for his exceptional intelligence, sarcasm, distrust of conventional authority, and dependence on a cane after a leg injury. His methods frequently violate hospital rules, but his diagnostic successes make him difficult to replace.

House is modeled partly on Sherlock Holmes. The connection appears in the names House and Wilson, House's use of deductive clues, and his willingness to pursue unusual explanations. The character's department is fictional, even though real hospitals may use multidisciplinary diagnostic services.
