I have taught 24 different courses on mathematics, statistics, measurement, and research methods at both undergraduate and graduate levels. At the University of Cincinnati, as a spearhead, I designed and established a Ph.D. program in Quantitative Research Methodology in 2003. Meanwhile, I developed a three-course sequence in Multivariate Analysis and a course on Quantitative Research Synthesis for the new Ph.D. program. After I came to Duke University in 2012, I redesigned a Ph.D. course on Measurement Theory and Practice to make it fit better to the program’s mission. I also initiated and have played a major role in the realignment of the Ph.D. statistics curriculum with students’ research needs.

I have mentored nine Ph.D. students and four Master’s students, and served as a methodological advisor on committees of more than 60 Ph.D. dissertations, seven Master’s theses, and four DNP capstone projects. My former doctoral advisees were awarded doctoral dissertation research grants from the National Science Foundation and the National Institutes of Health, received Outstanding Graduate Student and Outstanding Dissertation Awards from universities and nationally, and obtained tenure-track faculty positions at research universities upon graduation.
