My current research interests relate to the reciprocal adaptations of technology and delinquency, through the study of several particular forms of crimes such as identity theft, bank fraud, computer hacking or even telecommunications fraud. In particular, I examine the technological, criminal and control ecosystems that foster the emergence of certain types of illicit practices, as well as the processes by which offenders detect and take advantage of new opportunities. The questions of the acquisition of criminal skills, confidence, division of labor and modes of coordination are at the heart of my concerns. I am also interested in cybersecurity policies and various regulatory instruments forinternet which are gradually being set up in order to respond to the risks linked to cybercrime, cyber espionage or cyber attacks.
