What is the full name of House M.D.'s diagnostician commonly known as Dr. Chase?

The diagnostician commonly known as Dr. Chase is Robert Chase in House M.D. Australian actor Jesse Spencer portrays Chase, who is one of the doctors selected for House's original diagnostic team.

Chase is an intensivist and later develops a more independent medical identity as the series progresses. His background, loyalties, and relationship with House change over time, especially as the original team disperses and later returns in different professional circumstances.

The character's name is Robert Chase, not Jesse Spencer, which is the actor's name. He is also distinct from Eric Foreman and Allison Cameron, the other two doctors in House's original team. The full name helps separate him from the shorthand “Chase” used throughout most of the dialogue and promotional material.
