Trained as a cultural anthropologist, I have also published and taught extensively in sociology. I have long been fascinated with why people and groups get involved in particular activities, and thus have written on topics such as Star Trek fans, death celebrations in Africa, and video gaming. In current research, I focus on different subcultures and subgroups, including those that are countercultural. I address some of the implications for issues of economic equality.
Nonprofits provide a fascinating insight into this diversity, since they deal with it every day in their efforts against inequality.
