Crescenzo is a PhD candidate at Maastricht University (School CAPHRI, Care and Public Health Research Institute; Faculty of Health, Medicine and Life Sciences; Department of Health, Ethics and Society). The aim of their doctoral research is to explore how currently illicit substances are medically legalised, what human and non-human actors are involved in this process and how they are involved in it, what relationships exist between evidence and policymaking in this sector, how these processes are influenced by the socio-political and economic context, and what subjectivities, identities and ethical implications are emerging from this context. They have previously completed a bachelor’s degree in Sociology at the University of Naples, Federico II (Italy), and a Master of Science in Social Research at Birkbeck University, London (UK). They also are part of the National Centre for Social Research (London, UK) where they work as a Senior Researcher in the Centre for Health (Health Policy Team). In this role, they have conducted studies and evaluations on subjects such as drug use, bereavement, loneliness, and gambling, and co-authored several reports (most recently, on the use of cannabis and non-opiates among people from minority ethnic groups in England).
