Current Research

Pragmatic clinical trials

My research primarily focuses on developing methods in design and analysis of randomized controlled trials. The details of my research are:

  • Practical issues in cluster randomized trials

    • Design issues in cluster randomized trials
    • Statistical modeling in longitudinal cluster randomized trials (e.g., Stepped-wedge cluster randomized trials)
    • Clustered/longitudinal data analysis

  • Bayesian platform and adaptive trials

    • Optimize trial design
    • Bayesian inference in clinical trials
    • Bayesian prior elicitation

Quasi-experimental design

  • Interrupted time-series design
    • Multiple baseline interrupted time-series (MBITS) design
    • Statistical modeling in MBITS

Statistical Consulting

  • Impact in healthcare
    • Emergency medicine
    • Critical care
    • Cardiovascular risk
    • Mental health: depression and mood disorder
    • Alzheimer’s Disease and Related Dementias (ADRD)
