Dr. Chase’s first name is Robert in House M.D.
Robert Chase is one of the three doctors selected for House’s original diagnostic team, alongside Allison Cameron and Eric Foreman. Jesse Spencer played the character, who begins the series as an intensive-care specialist and later develops a broader role at Princeton-Plainsboro.
Chase’s professional background and family history become recurring parts of the series. His father, Rowan Chase, is a prominent physician, and their strained relationship affects Chase’s ambitions and self-image. Chase also experiences major changes in his personal life and medical career across the show.
The character remains with the series longer than most members of House’s early team. By the later seasons, Chase has become a more experienced physician and eventually assumes leadership of the Department of Diagnostic Medicine after House’s departure from the hospital.
