The overarching goal of Dr. Mitchell's research is to help prevent chronic diseases in later life, by focusing on energetic behaviors (sleep, diet, and physical activity) and their impact on body composition during growth and development. 

The Mitchell lab includes the Unit for Energetic Behavior Research that conducts multidisciplinary epidemiological studies, using sensors to measure locomotor activity, advanced imaging to measure body composition, detailed nutritional assessment to measure energy intake and dietary behavior, geospatial methods to measure the neighborhood environment, and DNA collection for gene-behavior interaction analyses. In addition, the lab’s Unit for Optimizing Behavioral Interventions uses the Multiphase Optimization Strategy framework to design digital interventions to improve energetic behavior profiles in childhood.

Effects of Sleep on Bone Density and Strength in Adolescence: A Prospective Longitudinal Study
NIH/NICHD (R01 HD100421-01)
2020-2025
The objective is to determine if sleep duration, timing and quality associate with changes in bone density and strength in early adolescence (ages 12-15y).

Sleep Extension and Enhancement Possibilities in Youth 2.0 (SLEEPY 2.0)
NIH/NICHD, R01HD108243-01
2022-2027

The objective of this study is to engineer a mobile health platform for the pediatric care setting to promote longer sleep duration for childhood obesity prevention. Our central hypothesis is that we will identify an optimal set of intervention components to increase sleep duration and prevent excess weight gain, with equitable effectiveness across sociodemographic backgrounds.
