Who is Diana Hartrick from Galatea 2.2 and what is their importance?

Diana Hartrick is one of the members of the team that Richard and Lentz are trying to prove wrong. Diana has been at U. for five years though she used to live in California. She is one of the first women that Richard comes into contact with after his break-up with C. Her specialty at the center is doing "associative representation formation in the hippocampus". A great deal of her work revolves around dissecting hippocampi from monkeys in order to study how the brain functions. She is one of Lentz's biggest critics and receives a lot of negative comments from him.
