Reuters is reporting that Amber Tamblyn (Joan of Arcadia) has joined Fox's House M.D. for a multi-episode arc.

The actress is going to play a highly intelligent medical student who comes aboard Dr. House's team. However, "she's not yet certified to practice medicine, and is confronted with the ethically questionable ways that the good doctor operates."
