My research is centered on social networks, with emphases on health, adolescence, and delinquent populations. I have developed a research program built upon two related questions:

• How do social networks impact critical developmental and health-related outcomes?

• How do people acquire their respective network positions?

Oftentimes I focus on adolescent school-based networks though I have recently become interested in networks among prison inmates. I use a variety of analytic methods, most often statistical network models (SIENA and ERGMs), but also simulations and the occasional regression. My work has been generously funded by the National Science Foundation, National Institutes of Health, and William T. Grant Foundation. I’m most proud of receiving the Freeman Award from the International Network for Social Network Analysis.
