Susan Colman

 was an associate researcher at the Lashley Institute.

One of her duties was to test Imogen Quaye's brain development after surgery had been done on Imogen's brain to improve her brain capacity.

When Colman was nineteen, she became pregnant but terminated the pregnancy. Imogen used Colman's guilt to telepathically induce her to commit suicide. Colman slit her wrists. (PROSE: Artificial Intelligence)
