Dr. Campbell studies oceans governance broadly, in relation to diverse issues (blue economy, blue carbon, protected species, fisheries, MSP, MPAs, tourism, etc.), and formal and informal processes. She draws on theory from political ecology, political economy, and science and technology studies to study how science and other values, the state and non-state actors, inform governance processes and outcomes across geographic and socio-political scales. She is more generally interested in innovation in research methods, e.g. Collaborative Event Ethnography and Community Voice Method, and has published on participatory research, collaborative research, inter-disciplinary research, field work, and research ethics.
