Research Interests

My research interests mainly lie in the investigations of 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, and multilevel modeling in broad social and educational contexts. Currently, I am serving as a statistical and methodological advisor of the Journal of School Psychology, an associate editor of Frontiers in Education – Assessment, Testing and Applied Measurement, and a consulting editor of the Journal of Experimental Education.
