Research Interests

My research interests primarily focus on investigating the performance and utility of current and emerging measurement frameworks that can provide formative and diagnostic information about student learning and achievement in various assessment settings. Particularly, I am interested in both methodological and applied aspects of (multidimensional) item response theory models, cognitive diagnostic models (CDMs), subscore reporting, differential item functioning (DIF), and large-scale assessment. I am also interested in applying statistical methods, such as missing data analysis, structural equation modeling, machine learning, and (longitudinal) multilevel modeling in broad educational and psychological contexts. Currently, I am the director of the WSU Large-Scale Data (LSD) Laboratory.
