Volunteering, Social Networks


Research Interests

I conduct research on the social and demographic correlates of volunteering.  Most of my recent work on volunteering utilizes multilevel data and modeling techniques.  Additionally, I explore the properties of social networks across a variety of settings.  My social network research tends to be collaborative and interdisciplinary, involving students and faculty from departments outside of Sociology.
