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.
