My research interests lie in the development, evaluation, and application of statistical methods to deal with clustered and longitudinal data in education, psychology, and behavioral science. My current work focuses on the evaluation and application of advanced modeling approaches to deal with various types of data (e.g., frequency counts, rates, and proportion data) from single-case experimental designs (SCEDs). I believe that the exploration of the potential of using statistical modeling tailored to different outcomes and designs in single-case studies can make a great contribution to the statistical rigor of SCEDs and have a broader impact on the evidence-based practice movement. From a substantive perspective, I am interested in applying advanced statistical methods to address practical issues in educational, developmental, clinical, and health research.
