  • Life-course health and networks

    Understanding how social ties to others at a given stage of one's life can shape one's future prospects. For instance, how does who you know when you were 5 years old affect your health at age 55?

  • Measurement of social networks

    Using wearable sensor and other passive technologies to measure social relationships and their sequelae in ways that complement (and sometimes challenge) prior self-report or observational approaches to understanding social structure. In what ways does precise quantification of interactions provide new insights into social dynamics? In which cases does an individual's own perceptions of their relationships provide useful information?

  • Social networks and health

    Evaluating how individuals' social relationships and interactions shape their health behaviors. For example, how do a person's changing set of relationships with people in their lives affect their health-related decisions, physical health, and mental health?


I welcome research partnerships that relate to social networks, culture, and health across the lifecourse, and am a firm believer in team-based science. I collaborate widely with colleagues and students - I hold the view that working on problems from multiple perspectives advances scientific progress.
