Benoit Viguier [--cv] ... [--gh] [--gl] [--mail]
Benoit Viguier is a PhD student at the Digital Security group and the
Department of Software Science of the Radboud University in Nijmegen,
working on tools for formally verifying cryptographic software under the
supervision of Peter Schwabe, Freek Wiedijk, Joan Daemen and
Herman Geuvers. Before that, he was an engineering student at the
INSA Rennes (National Institute of Applied Science, France) and master
student in Research in Computer Science (MRI).
