Healthy Homes, Healthy Habits

In this study we build on the strengths of established Home Visitation Programs, which serve at-risk, low-income, diverse mothers and their infants, to test a weekly, in-home childhood obesity prevention model. We promote healthy eating and activity habits in the family, and modify the home environment and families' social networks so that they provide support for their healthy habits.

Using Big Mobility Data to Map Food Environment Dynamics

This study uses large scale human mobility data—geolocation information from our cellphones—to gain new insights about the quality of food environments people are exposed to as they move throughout the day, and test if these food environments influence our food choices. We partner with Los Angeles County government to identify strategies to use these new insights to improve healthy food access, diets, and health.

Network Science of Teams

This Multi-University Research Initiative (MURI) supports a multidisciplinary team with expertise in cognitive and behavioral science, sociology, computer science, network science and statistics to generate multilevel, dynamic models of teams that explain various dimensions of performance and success. The resulting conceptual and statistical models that relate group composition, interaction patterns, and network evolution to task performance, will break new ground in understanding the optimal design of teams for complex tasks.

Monitoring and Modeling Family Eating Dynamics (M2FED)

This project proposes M2FED – a system of in-home beacons, wireless and wearable sensors, and smartphones that provide real-time data on families eating in the home. The goal is to monitor and model family eating dynamics in real time, and ultimately  develop  just-in-time, adaptive interventions.
