David Décary-Hétu Prof. Décary-Hétu has a Ph.D. in criminology from the University of Montreal. He has worked as a Senior Scientist at the School of Criminal Sciences of the Université de Lausanne before his current position as an Assistant Professor at the School of Criminology of the University of Montreal. His thesis focused on the impact of the Internet on crime as well as how offenders have adapted to the virtual environment. Prof. Décary-Hétu has since continued his research on online illicit markets and is now particularly interested in cryptomarkets, 2nd generation online illicit markets. He has developed the DATACRYPTO tool that he uses to collect large amounts of information on cryptomarket participants. His research goals are to better understand the structure of markets and the social network of actors who participate in them as well as to understand the performance in the context of online illicit markets. To achieve these objectives, Prof. Décary-Hétu uses a quantitative approach that takes advantage of big data, data mining and social network analysis. The results of his research, funded by both the provincial and federal governments, have been published in journals such as the Journal of Research in Crime and Delinquency, have been presented at numerous conferences and have been disseminated to a wide audience in a number of interviews with the media.
