Research Summary

My research focuses on developing and improving psychometric methods for educational assessments. By improving psychometric methodology, I seek to improve the utility of assessments. My goal is to help provide students, teachers, and researchers with actionable information they need, value and can trust.

My work has contributed to advancements in multidimensional item response models called diagnostic classification models (DCMs). DCM-based methods I have designed are used to provide fine-grained diagnoses of students' complex knowledge structures, which include concepts students understand as well as misconceptions they have.

Intersecting my background in mathematics education with psychometrics, my research also includes collaborating with interdisciplinary teams to create diagnostic assessments. Currently, I am working with PARCC, a consortium of US states, to develop a classroom-based diagnostic assessment system for K-8 mathematics.
