About Dr. de la Haye

Kayla de la Haye is an Assistant Professor of Preventive Medicine at the Institute for Health Promotion & Disease Prevention Research (IPR) within the Department of Preventive Medicine, USC.
She specializes in applying social network analysis and systems science to health promotion and disease prevention. Her work has examined the spread of obesity in adolescent social networks, and how social-ecological systems influence health behaviors (diet, physical activity, substance use) in youth and families. She is also working to develop interventions that enhance or alter social networks and social systems to increase healthy behaviors and reduce disease in at-risk communities.
Dr. de la Haye holds a Ph.D. in psychology from the University of Adelaide, Australia.

Dr. de la Haye’s Research Interests

Some of my current research projects include:

COPE: Childhood Obesity Prevention at homE
• This study capitalizes 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, evidence-based childhood obesity prevention model (COPE) delivered in the first 2 years of children’s life. COPE targets important maternal and social network mechanisms to support the adoption and maintenance of healthy eating and activity in low-income families.
• My role: Co-Primary Investigator (Co-PI: S.J. Salvy)

Monitoring and Modeling Family Eating Dynamics (M2FED): Reducing Obesity Without Focusing on Diet and Activity
• This project proposes M2FED – an integrated system of in-home beacons, wireless and wearable sensors, and smartphones that provide real-time data on in-home eating behaviors and social dynamics. This rich data will be aggregated to generate real-time models of Family Eating Dynamics, that can ultimately inform future just-in-time, adaptive interventions.
• My role: Co-Primary Investigator (PI: D. Spruijt-Metz)
• Funder: National Science Foundation

QUANTA: Quantitative Network-based Models of Adaptive Team Behavior
• In this project our multi-institutional team will use expertise in cognitive and behavioral science, sociology, computer science, and network science to generate dynamic models of teams and social groups that effectively explain various dimensions of group performance and problem-solving.
• My role: Primary Investigator at USC
• Funder: Army Research Office
