I finished my Ph.D. in quantitative psychology at UIUC in 2017. After spending the 2017-2018 academic year as a visiting assistant professor of quantitative psychology at the University of California, Merced, I made my return to UIUC as assistant professor in the educational psychology department. My primary area of research is in educational and psychological measurement, with a focus on computer adaptive testing, the use of response times in testing, ideal-response models, and cognitive diagnostic modeling. More broadly, I am interested in the improvement of methods used for analyzing multivariate data in the behavioral sciences as a whole. As a methodologist, I have a special interest in working with others, and I look forward to future collaborations within education, psychology, and other behavioral sciences around the UIUC community.

Advanced Statistical Methods (EPSY 582) Prerequisites are enforced and those not meeting them will be asked to drop or will be dropped from the class.

Theories of Measurement II (EPSY 586) Provides a conceptual framework of Item Response Theory (IRT) and its applications. Students will learn the techniques and theory of IRT and apply the methods to educational and psychological assessments. Topics covered include both dichotomous and polytomous IRT modelling, item structure and latent traits estimation, modeling and detecting Differential Item Functioning, linking and equating, computer adaptive testing, dimensionality testing, and cognitive diagnosis.
