My statistical research interest includes: sample size determinations for clinical trials including cluster randomized trials and stepped-wedge trial; meta-analysis; longitudinal data analysis applying mixed-effects models; handling attrition problems in clinical trials data; and statistical consulting and mentoring. I am also interested in epidemiology research in the field of obesity, HIV and HCV infections.
