UNODC under its Education for Justice (E4J) initiative, in cooperation with the European Consortium for Political Research (ECPR) and its Standing Group on Organised Crime (SGOC), held a two-week Winter School on Organised Crime in Vienna (Austria), between 13 and 24 January 2019. During this Winter School, more than 40 participants from over 20 countries across the world had the chance to learn from academics and United Nations experts as well as engage in discussions and critically reflect about the challenges posed by organized crime. The group of participants was primarily composed by PhD students and lecturers who were selected by SGOC after a competitive application process. The programme of the Winter School touched upon many of the topics covered in the Organized Crime Module Series, which were presented during the programme and used as a basis for discussion.
