This article contributes to discussions of a public anthropology by bringing participatory action research (PAR) into dialogue with anthropology. PAR appears uniquely compatible with the goals of critical ethnography. Deeply concerned with global/structural inequality, it is also attentive to the power relations inherent within the research encounter; its point of departure is the kind of collaboration that the new (critical) ethnography proposes. However, despite these obvious affinities, few anthropologists have engaged PAR. At a time when more and more anthropologists are advocating forms of collaborative research practice, I argue that these two approaches to research can offer each other a great deal and that juxtaposing them is productive. Tracing the stages of my own fieldwork in post-Soviet Russia, I argue that PAR offers the ethnographer a stance, or a framework to affect public anthropological engagement in the field. Further, it offers a means by which we can bring critical anthropological insights to collaborative projects for social change.
