Assistant Professor of Sociology and Criminology and Criminal Justice

Cassie McMillan’s research applies a social networks perspective to disentangle how our connections both reproduce and challenge systems of social inequality. She is interested in developing statistical and computational methodologies that can better address these questions and applying these techniques to study adolescent delinquency, health, and immigration. Her current research projects examine how social network ties that persist from adolescence to adulthood shape trajectories of tobacco, alcohol, and substance use across the life course. Results from this work will uncover the ways that our social network structures inform disparities in substance use and recovery. Other recent projects consider how adolescent friendship and dating patterns collectively shape the diffusion of sexually transmitted infections (STIs), as well as the role that youth networks play in shaping adolescents’ experiences with bullying and aggression.
