Eric Foreman

During the first three seasons, House's diagnostic team consists of Dr. Robert Chase (Jesse Spencer), Dr. Allison Cameron (Jennifer Morrison), and Dr. Eric Foreman (Omar Epps). At the end of the third season, this team disbands. Rejoined by Foreman, House gradually selects three new team members: Dr. Remy "Thirteen" Hadley (Olivia Wilde), Dr. Chris Taub (Peter Jacobson), and Dr. Lawrence Kutner (Kal Penn). Chase and Cameron continue to appear occasionally in different roles at the hospital. Kutner dies late in season five; early in season six, Cameron departs the hospital, and Chase returns to the diagnostic team. Thirteen takes a leave of absence for most of season seven, and her position is filled by medical student Martha M. Masters (Amber Tamblyn). Cuddy and Masters depart before season eight; Foreman becomes the new Dean of Medicine, while Dr. Jessica Adams (Odette Annable) and Dr. Chi Park (Lo Mutuc) join House's team.
