This panel explores a range of methodological approaches to the study of radicalism and violence across disciplines, drawing on the panelists' recent qualitative and quantitative empirical work.  Individual papers report on studies grounded in the analysis of iconography and visual data; of survey data; of historical case studies (event history analysis); and of mixed methods data including interview data and document analysis in addition to quantitative data.  Through a focused discussion with the panel moderator, panelists will discuss methodological challenges and dilemmas to conducting research on radicalism and violence in Europe.
