Dr. Hartwell’s research has focused on public health topics - food security, addiction, nutrition, and exercise, using an array of statistical and mapping tools and techniques. He obtained his PhD from Oklahoma State University’s REMS program with emphasis in applied statistics, which provided an opportunity to analyze social and nutritional behaviors and biomarkers with NHANES data and publish a best practices manuscript on using structural equation modeling with complex survey data.  The work won first place in the Methods category at the 2018 American Society of Nutrition Conference and received a Graduate Research Excellence award. He has over 20 peer-reviewed published manuscripts and presentations and has partnered with Feeding American and Cornell to publish technical reports of behavioral economics within food pantries and food banks, the OSU FAB study to assess nutrient biomarkers and transdermal alcohol sensors, and is currently working with the OSU Center for Wellness and Recovery and the Laureate Institute for Brain Research to analyze MRI data of 9-10 children related to prenatal exposure.

Dr. Hartwell received additional statistical training from attending Johns Hopkins Bloomberg School of Public Health Summer Institute of Epidemiology and Biostatistics and University of Oklahoma College of Public Health, Department of Biostatistics and Epidemiology and Oklahoma Shared Clinical & Translational Resources in Bayesian analyses, clinical trials, and burden assessment and health economics.  In coordination with Dr. Matt Vassar, his current focus is to extend the office of medical student research further into improving the quality of clinical research as well as extending mentorship to more students.
