What is the name of House’s closest friend and Princeton-Plainsboro oncologist?

James Wilson is House’s closest friend and the oncologist at Princeton-Plainsboro Teaching Hospital in House M.D. His medical specialty and empathetic personality contrast with House’s abrasive methods and often cynical view of patients.

Wilson repeatedly supports, challenges, and sometimes enables House. Their friendship is one of the series’ most important long-term relationships, and Wilson’s personal and professional decisions frequently become central to major storylines.

Robert Chase and Eric Foreman are also physicians who work closely with House, but neither is his closest friend. Michael Tritter is a patient who becomes involved in a major conflict with House, not a member of the hospital’s regular diagnostic partnership.
