My research is in the area of Bayesian modeling and prediction. I am interested in methodological issues concerning the impact of modeling assumptions on the quality of model fit. I collaborate with Ohio State colleagues in statistics and psychology to develop statistical models that describe the cognitive processes involved in simple decision-making tasks.
