Research interests

My research interests pertain to innovative application of statistical methods in health research; these include application of an existing statistical method or development of (new) analytical (statistical) tools as warranted by the health research topic. My research finds their appreciation and application in various disciplines of applied science. Specifically, my research topics include:

  • Incomplete or missing data
  • Model selection
  • Longitudinal models
  • Computational statistics
  • Signal saturation rates

The above topics have been used extensively in dissertations (21+) and papers (16+) authored by students who I have mentored as a committee member or supervisor. Since joining the School of Public Health and Health Systems in September 2015, these topics have been used to address pressing questions in the areas of nutrition, epidemiology, cancer care, pediatrics, nephrology, workers health, aging, maternal and child health, and more. A list of my citations can be found on my Google Scholar page.
