Jesse Spencer played Dr. Robert Chase in House M.D.
Chase is an Australian intensivist who begins the series as one of the original members of House’s diagnostic team. His background, ambition, and willingness to challenge authority give him a different perspective from House’s other colleagues.
The character remains connected to the series after the original team changes. Chase develops professionally and personally, eventually taking on greater responsibility at Princeton-Plainsboro. His specialty and career path are part of the show’s broader interest in how doctors grow beyond House’s immediate influence.
The surname is easy to confuse with Foreman, Taub, or Kutner, who are also members of House’s teams at different points. Jesse Spencer’s role as Chase was one of the actor’s best-known television performances before he later starred in Chicago Fire.
