DORI brings together a diverse group of researchers spanning over 26 divisions & departments across the University of Southern California.

All of Us Research Program

The All of Us Research Program has a simple mission. We want to speed up health research breakthroughs. To do this, we’re asking one million people to share health information. In the future, researchers can use this to conduct thousands of health studies. Participants must be 18 years of age and over.

BrainChild Study

This study looks at the risks for diabetes and obesity in children whose mothers had diabetes during pregnancy. We hope to learn about how being exposed to diabetes in utero may affect risk for diabetes and obesity in children. In particular, we are interested in examining behavior and brain development in children whose mothers had gestational diabetes mellitus (GDM).

Brain Response to Sugar

This study is about how the brain responds to different types of sugars. Particularly, how the brain responds to glucose, fructose, and sucrose, and how this response may be different in young people who are overweight and obese compared to those who are normal weight.

Genetics of Liver Fat (GoLF) Study

The Genetics of Liver Fat (GoLF) Study is examining how differences in genes (the “blue print” for all inherited traits) may determine why some people are more likely to develop fat in their liver and how that fat level contributes to the risk for type 2 diabetes.

Mitochondrial Derived Peptides Research

The Cohen lab investigates the role that mitochondrial derived peptides play in obesity and diabetes and their possible use as novel therapeutics.

Mothers' and Their Children's Health Study (MATCH)

The MATCH Study examines how maternal stress may compromise parenting practices related to their children’s dietary and physical activity, and contribute to obesity risk over time.

Sedentary Behavior and Health Outcomes Study

This groundbreaking study will examine whether past energy balance behaviors predict the metabolic response to interrupting sitting time in healthy children. We will also study the effects of the social context and home environment on these energy balance behaviors and glucose homeostasis using ecological momentary assessment and continuous glucose monitoring.

This study will inform future targeted intervention strategies to prevention or ameliorate the consequences of childhood obesity and type 2 diabetes.

TIME Study

The TIME Study uses smartphones and smartwatches to collect intensive longitudinal data to examine how psychological and contextual factors affect the adoption and maintenance of physical activity, sedentary, and sleep behaviors across 12 months in young adults.

Specific Research Areas of Interest

To facilitate collaboration and guide the development of the Institute, the DORI developed an initial seven research categories, to provide a forum for topical discussion and the development of collaborative pilot studies.  

These are by no means research “silos”, rather broad topics to be researched and attacked from diverse perspectives.  

Researchers meet individually and through periodic Institute retreats that offer opportunities for collaboration, learning, and pilot study funding. As the Institute develops, additional research areas will be developed.
