      Collapse Overview
      Kayla de la Haye is an Assistant Professor of Preventive Medicine at the University of Southern California, and specializes in applying social network analysis and systems science to health promotion and disease prevention. She has examined the spread of obesity in social networks, and produced innovative findings that peer network effects on obesity-related behaviors are important mechanisms underpinning this phenomenon. She is involved in several projects that explore how social systems influence health behaviors (diet, physical activity, substance use) in youth and families, and is working to develop interventions that enhance social networks to increase healthy behaviors and reduce disease among at-risk populations. Dr. de la Haye's is a member of the Board of Directors of the International Network of Social Network Analysis (INSNA), and is a consulting editor for Connections (the official journal of INSNA). She holds a Ph.D. in psychology from the University of Adelaide in Australia.

      Building Social Networks to Improve Physical Activity and Weight Loss in Latino Parents
      NIH/NICHD R01HD084606Feb 18, 2016 - Jan 31, 2019
      Role: Co-Investigator
      Role Description: This project examines the complex relationship between social networks and peer influences on Latino adult physical activity and obesity in order to understand which types of networks facilitate (and which constrain) the diffusion of physical activity and weight loss through a community.
      Whole of Systems Trial of Prevention Strategies for Childhood Obesity: WHO STOPS Childhood Obesity
      National Health and Medical Research Council (Australia) APP1114118Feb 1, 2016 - Jan 31, 2019
      Role: Associate Investigator
      Role Description: This project aims to: 1) strengthen community action for childhood obesity prevention; and, 2) measure the impacts of increased action on risk factors for childhood obesity by working with local partners to embed best practice for obesity prevention into existing community systems (e.g. health, workplaces, local council, schools).
      Monitoring and Modeling Family Eating Dynamics (M2FED)
      National Science Foundation IIS-1521740Sep 1, 2015 - Aug 30, 2019
      Role: Co-Principal Investigator
      Role Description: This project proposes M2FED – an integrated system of in-home beacons, wireless and wearable sensors, and smartphones that provide ongoing, synchronized real-time data on in-home eating behaviors and theory-based process variables. This rich data will be aggregated to generate real-time contextual FED models using systems networks models. Key activities that precede target behaviors will be identified in order to develop and optimize future just-in-time, adaptive interventions.
      QUANTA: Quantitative Network-based Models of Adaptive Team Behavior
      DoD/Army Research Office W911NF-15-1-0577Jan 9, 2015
      Role: Co-Principal Investigator
      Role Description: The multidisciplinary, multi-institutional team will utilize expertise in cognitive and behavioral science, sociology, computer science, and network science to generate multilevel, dynamic models of teams and social groups that effectively explain various dimensions of group performance. 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.
