Renaat Verbruggen studied at University College Dublin, obtaining a Bachelor's in Communication in 1980 and Masters in Management Information Systems in 1981. He then went to Belgium in 1982 to study at the Katholieke Universiteit in Leuven (KUL), there he completed a Doctorate in Toegepaste Economische Wetenschappen, or Masters in Information Science. He worked as a tutor at both UCD, KUL and then a lecturer at the RTC in Dundalk. He became an assistant lecturer in the then National Institute for Higher Education in 1986 and a full lecturer in Dublin City University in 1990.
His main area of work was Software Engineering and he developed and ran many modules in this area. He also worked closely with industry, establishing and delivering courses and working on action-research projects for many of the major consultancy companies and multinationals located in Ireland.
In 2003 he helped establish the M.Sc. In Security and Forensic Computing at DCU, the first such postgraduate degree in Ireland. Since then he has acted as director of this degree and concentrated on the ethical and legal aspects of cyber-crime and the internet. He has supervised and collaborated on many papers in the area and contributed to conferences in the areas of cyber-terrorism. Away from the internet he can be found wandering, like Aengus, amongst the Wicklow Hills and observing the wildlife, in particular his favorite the Daubenton's bat.
