About

Biography

As a professor and researcher, I design clinical and non-clinical studies, perform data analysis and presentation and examine mathematical modeling. My primary interests are probability and statistical theory applied to medical research, including distributional theory and optimization.

My interest in this field stems from my mathematical and statistical training and quantitative research. One of my notable discoveries is the probabilistic relationship between sample size and discovery rate in clinical studies, which can be reviewed in some of my publications.

I have been a researcher for over 29 years and began working with Cincinnati Children’s in 2012.
