In House M.D., who serves as the hospital’s chief of oncology?

In House M.D., James Wilson serves as Princeton-Plainsboro Teaching Hospital’s chief of oncology.

Wilson’s specialty shapes many of his storylines. Oncologists diagnose and treat cancer, often while helping patients and families make difficult decisions about prognosis and treatment. The series uses Wilson’s work to show a different kind of medical uncertainty from House’s: oncology frequently involves balancing aggressive treatment, quality of life, and a patient’s wishes.

Wilson is also Gregory House’s closest friend and a frequent source of practical and moral advice. Their professional roles complement each other. House searches broadly for explanations in diagnostically baffling cases, while Wilson focuses on cancer care and the human consequences of serious disease.

Robert Sean Leonard portrays Wilson. The character’s title is sometimes confused with hospital-wide leadership, but he is not the dean of medicine; Lisa Cuddy holds that administrative position. Wilson’s specific leadership post is chief of oncology, and his office and consultations recur throughout the series.
