This essential handbook provides researchers, educators and policymakers with the tools and critical reflections needed to navigate the complexities of GBV research, from conceptualisation and fieldwork to dissemination and impact. Carefully curated essays from leading scholars and practitioners in the field examine the interconnected epistemological, methodological, and ethical dimensions of GBV research. They offer new perspectives on how researchers formulate, design, and conduct research in changing knowledge production landscapes. Through global research experiences, the handbook explores not only the critical questions researchers face, but also the innovative strategies they employ in this complex field of enquiry. Key topics covered include: intersectional perspectives on neurodiversity and power relations in academic research; GBV in the context of debates around the concept of gender; GBV as an analytical tool and as an observable phenomenon; the challenges and opportunities of conducting feminist research on GBV; epistemological violences and the study of GBV against transgender-identified people; GBV in university contexts and the triple roles researchers face as teachers and providers of pastoral support; feminist research ethics; methodological designs to explore silence in GBV; the dilemmas of perpetrators’ participation in research; the use of digital media as a way to conduct and trace GBV in ever more online social interactions; the use of quantitative methods and its challenges to shed light on historically ignored forms of GBV; the practical and analytical implications of conducting international surveys and within larger policy and advocacy strategies; explorations on the use of arts in research, from music elicitation to Butoh dance; intersectionality in fieldwork practices; the problematisation of taken-for-granted GBV concepts; participatory and collaborative research methods, ethics and analytical frameworks; the policy and advocacy uses of research and its dilemmas in third-sector organisations; and the use of social theory as an analytical and practice-based transformative tool. The Routledge International Handbook of Gender-Based Violence Research is a landmark resource for graduate students, scholars, applied researchers and policy practitioners critically engaging with the nexus of epistemology, methodology, and ethics in research and more specifically in the study of gender, violence, and social inequality.
