Why are there stable cross-country differences in suicide rates?
How can autism prevalence increase so rapidly?
My research focuses on social networks and health, micro-macro links, and the diffusion of non-contagious conditions. I argue that networks are crucial to solving epidemiological puzzles.
My research has appeared in American Journal of Sociology, Demography, Social Forces, International Journal of Epidemiology, and other journals.
I teach courses on quantitative research methods and network analysis.
