There are currently five faculty in the quantitative psychology program. In addition, several affiliated faculty in other areas have strong quantitative backgrounds and interests, and interact with quantitative faculty and students on a regular basis. Several of our faculty are also associated with cross-disciplinary research areas such as Decision Psychology.
