Department of Nutritional Sciences

My position as a biostatistician requires me to be a jack-of-all-trades, so I have experience with design of experiments, analysis of mRNA and sequence data, and cancer and obesity research, to name a few areas. My research interests are in the proper measurement of nutritional outcomes, especially outcomes that are primarily obtained via self-report and hence may be invalid, unreliable, or both. I have a joint appointment with the Center for Biotechnology & Genomics and collaborate within and beyond the College of Human Sciences.
