On the 30th of October 2017 I participated in a Guest Editors writing workshop at the Peace Research Institute Oslo (PRIO) with my colleagues Rocco Bellanova and Mareile Kaufmann. The workshop served as a setting in which to finalise plans for the editorial introduction to our forthcoming special issue of the leading security studies journal Security Dialogue, based at PRIO, and which includes contributions from leading thinkers within the field as well as new and innovative voices. The special issue focus on cutting-edge issues on ‘doing and mediating critique’ within security studies.
