There are currently four faculty in the quantitative psychology program. In addition, several faculty in other areas have strong quantitative backgrounds and interests and interact with quantitative faculty and students on a regular basis.

Gyeongcheol Cho

Assistant Professor; Ph.D., McGill University, 2023. Advancing quantitative methods to explore and confirm the intricate relationships that exist between human behavioral, psychological, and biological variables, with a special emphasis on the measurement of theoretical constructs.

Michael DeKay

Associate Professor; Ph.D., University of Colorado, 1994 - Judgment and decision making. Current work: risk perception, precautionary reasoning, information distortion in risky decisions, perceived fungibility of outcomes in repeated-play decisions.
