What are the social causes and consequences of social networks across society and time? My scholarly work connects and contributes to three specialty areas: social networks, medical sociology, and social stratification. I investigate three major research themes: how social networks produce inequalities in health and well-being, how social networks generate social stratification, and how social forces stratify social networks. The network-based concepts I analyze include accessed status (network members’ status), social capital, social support, social integration, reference group, social comparison, social cohesion, and tie strength. The social stratifiers I study include age, gender, race/ethnicity, SES, and class. The major well-being outcomes I examine include health, health information search, life satisfaction, lifestyle, body weight, and genetic privacy. Link to my Curriculum Vitae and Google Scholar.
