Our Team

We are a collective of innovators and thinkers dedicated to the idea that research and community well-being go hand-in-hand.


We come from diverse backgrounds, but together make a strong team.


As a team, we are united by a common interest in research on community and public health.  We use methods like ethnography, assessment, and network analysis to better understand and serve our research hosts and the public policy makers that shape their lives. Our work has been funded by the National Institute of Health, the National Science Foundation, the US Centers for Disease Control, the National Institute of Justice, and others. We specialize in research on “hard-to-reach” populations in both the social and geographical senses of the term. This work has taken us from the Arctic to the Caribbean, and from the East Coast to the West. Interested students can reach us via email (kdombrowski2@unl.edu) or via the Sociology Department at the University of Nebraska-Lincoln (www.soc.unl.edu). Past members of our group now serve as faculty and researchers at the University of Minnesota, Oklahoma University, Haverford College, Pennsylvania State University, and many others.
