Which character in House M.D. was played by Australian actor Jesse Spencer?

Jesse Spencer played Dr. Robert Chase in House M.D. Chase is an Australian physician and a member of House’s original diagnostic team at Princeton-Plainsboro Teaching Hospital.

The character initially works in intensive care and later develops a surgical career. His background, changing specialties, and evolving confidence give the show opportunities to explore professional identity and the pressures of working under House.

Spencer was born in Melbourne, Australia, and was already known in Australian television before House M.D. He later became widely recognized in the United States through the series Chicago Fire, where he played Matthew Casey.

Chase is sometimes confused with other original team members because the first diagnostic group includes Foreman and Cameron as well as Chase. Omar Epps played Foreman, and Jennifer Morrison played Cameron. Jesse Spencer’s character is specifically Robert Chase, whose Australian background is part of his early characterization.
