Research Interests

My research focuses on advanced psychometric models, including mixture IRT and SEM, and their applications in educational and behavioral sciences, with a particular emphasis on differential item functioning (DIF) analysis and measurement invariance in both large- and small-scale assessments. My dissertation examined an extended mixture item response model incorporating a covariate variable. More recently, my work integrates psychometrics with artificial intelligence (AI), including automated item generation (AIG), AI-driven assessment validation, and large language model (LLM) applications in educational testing, with an overarching aim of developing adaptive assessments, detecting item bias, and enhancing fairness and efficiency across diverse learner populations.
