As a biostatistician, I focus on developing and evaluating statistical methods that are useful for medical research, with an emphasis on estimation in the context of the following substantive areas:

  • Cluster randomization trials.

  • Genetic association studies.

  • Health-related quality of life.      

  • Health economic evaluation. 

  • Prospective epidemiological studies.
