Sarah has been a Registered Dietitian since 2003 and currently serves as the Director of Dietetics Training for the University of Michigan School of Public Health in the Department of Nutritional Sciences. She has extensive experience in designing, implementing, and evaluating child obesity prevention interventions in child care settings and in dietary assessment methods for clinical and public health research settings. She has a personal interest in field of precision nutrition, disease prevention, and using food as medicine with the hopes of inspiring the next generation of dietitians to develop an interest in these as well. Additionally, she serves as Manager of the Nutrition, Exercise, and Phenotype Testing Core for the Michigan Nutrition Obesity Research Center and co-teaches NUTR 597: Precision Nutrition – Translating the Science to Practice.

Jeff Horowitz is a Professor in the U-M School of Kinesiology, where he directs the Substrate Metabolism Laboratory. His laboratory studies the regulation of fat, carbohydrate, and protein metabolism in humans, with particular interest in how exercise and diet affect lipid metabolism and insulin resistance in obesity. Dr. Horowitz’s laboratory focuses on identifying adaptions (at the cellular, tissue, and whole-body level) in response to exercise and/or dietary intervention that may impact important clinical outcomes, which could lead to improved methods to treat chronic diseases. Dr. Horowitz earned a BSE in Biomedical Engineering from The University of Iowa (1989), as well as an MA (1992) and a PhD (1996) in Exercise Physiology (both from The University of Texas at Austin).

Alison Miller is a developmental psychologist who studies risk and resilience in children and families.
