There are currently five 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.

Paul De Boeck

Professor, Ph.D., KU Leuven (Belgium), 1977 - Generalized linear mixed models and item response theory with a focus on explanatory models, applications to intelligence, personality, and educational measurement.

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.

Andrew F. Hayes

Quantitative Professor; Ph.D., Cornell University, 1996 - Resampling based methods of inference (such as bootstrapping and permutation tests), small sample data analysis, consequences of assumption violations in linear models as well as mediation and moderation analysis. (Primary Appointment at School of Communication).


Jolynn Pek

Assistant Professor; Ph.D., University of North Carolina at Chapel Hill, 2012 - Quantifying uncertainty inherent in results obtained from fitting models to data, especially latent variable models.  Understanding the limits of statistical results and ascertaining statistical conclusion validity is central to her work.


Trisha Van Zandt

Associate Professor; Ph.D., Purdue University. 1992 - Mathematical models of simple decision making in memory and cognition, quantitative methods. Current work: mathematical models of confidence in memory retrieval, and statistical methods for reaction time analysis.


Emeritus Faculty


Hal Arkes

Professor; Ph.D., University of Michigan, 1971 - Human judgment and decision making. Current work: sunk cost effect, disaggregated vs. holistic methods of evaluation, decision making among seriously ill patients and their physicians. Editorial Board: Journal of Behavioral Decision Making, Organizational Behavior and Human Performance. Joint Appointment in the Center for Health Outcomes, Policy, and Evaluation Studies.

Nancy Betz

Ph.D., University of Minnesota - Measurement, with a focus on classical test theory, psychological testing, measurement and use of personality variables in vocational behavior and decision-making.

Michael W. Browne

Professor; Ph.D., University of South Africa, 1969 - Multivariate quantitative methods for use in psychological research; properties and performance of quantitative methods, especially linear latent-variable models. Current work: Nonstandard simplicity functions for analytic rotation; Asymptotic distributions for rotated factor loadings; Properties of models for multitrait-multimethod data; Models for repeated measurement. Associate Editor: Psychometrika. (Jointly with Statistics)


Robert Cudeck

Professor; Ph.D, University of Southern California, 1980 - Applications of structural equation models and random coefficient models to psychological data.

Thomas E. Nygren

Associate Professor; Ph.D., University of Illinois. 1975 - Mathematical and cognitive psychology; mathematical models of decision making; measurement theory; psychological scaling. Current work: judgment and decision making; subjective uncertainty estimation; mental workload assessment; additive models and conjoint measurement.
