What specialty does Robert Chase practice in House M.D.?

Robert Chase practices intensive care medicine in House M.D. He is an Australian physician and one of the original members of House’s diagnostic team.

Chase’s medical background is broader than the title of a single episode or department might suggest. The character begins as a fellow working under House and later develops into a more independent physician. His clinical skills, procedural knowledge, and willingness to adapt help him remain important as the diagnostic teams change.

Viewers sometimes identify Chase only as a surgeon because surgery is a prominent part of his later professional development. His listed specialty is intensive care medicine, while the show also depicts him working across diagnostic and surgical settings. Jesse Spencer played Chase throughout the series, making him one of the longest-serving members of House’s medical circle.
