Research Description: 

My research in biostatistics is strongly motivated by collaborative work in the areas of HIV, cardiovascular disease, diabetes and cancer and is firmly rooted in addressing analytical challenges with applications in public health. In particular, my research involves development and application of statistical methods for:

  1. Designing and analyzing outcomes related to HIV-related clinical studies
  2. High-dimensional data settings (p >> n), as seen in genetic, proteomic and metabolomic studies
  3. Time-to-event outcomes subject to misclassification, as encountered in large-scale epidemiological studies such as the Women’s Health Initiative
