As with many large NIH-funded cardiometabolic study biorepositories, the UVT Biorepository run by Russ Tracy served the CALERIE study as its biorepository. Not only did the institution receive, store and catalog our samples, it performed much of the lab-based assays for the trials, and distributed samples until they were transferred to the NIA Research Biorepository. Perhaps most important, Russ served as a font of knowledge about how to manage a study biorepository. His most memorable and helpful statement — "The only good biorepository is an empty biorepository.

Emma J. Stinson is a Statistician at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) in Phoenix, Arizona, and is currently pursuing a PhD in Biomedical Informatics and Data Science at Arizona State University. Her research focuses on the development and application of statistical and data-driven methods to study metabolic health, with an emphasis on energy intake and energy expenditure. She is the lead author of a recent Journal of Nutrition publication from the CALERIE study using machine learning to identify determinants of habitual preformed water intake. Her findings showed that data-driven machine learning models can identify novel dietary and physiological factors associated with habitual preformed water intake, relationships that may be missed using traditional statistical approaches, contributing to a deeper understanding of hydration and metabolic health.
