Dr. Spencer Reid (portrayed by Matthew Gray Gubler), is a Supervisory Special Agent. He is a genius who graduated from Las Vegas High School at age 12, and holds PhDs in Mathematics, Chemistry, and Engineering, as well as BAs in Psychology and Sociology, and, as of season four, is working on a BA in Philosophy. It has been revealed that he has an IQ of 187, can read a dizzying 20,000 words per minute, and has an eidetic memory. Most of the members on the team are intimidated by his profound knowledge. He is habitually introduced as "Dr. Spencer Reid", in contrast to the other agents' introductions as "Supervisory Special Agent". The purpose of this, as explained by Unit Chief Aaron Hotchner in the pilot episode "Extreme Aggressor", is to create a respectable first impression of Spencer, deflecting judgments about his age. His mother, Diana Reid (Jane Lynch), suffers from schizophrenia, and is currently committed to a mental institution. In the season seven episode "Proof", Spencer completely ignores SSA Jennifer Jareau for not telling him the that SSA Emily Prentiss was alive. Spencer is also the godfather of Jennifer's son Henry. In the eighth season Spencer is involved with a woman whom he has never met in person due to the fact she is being stalked. Reid watches her die the first time they ever meet in person when her stalker finally catches up with her in the episode "Zugzwang". The stalker commits murder-suicide. Reid is devastated by the loss but returns to work quickly.
