Sandrine Blazy

I am professor in the computer science department (ISTIC) of the University of Rennes 1.

I am a member of CELTIQUE, a joint project-team with INRIA Rennes Bretagne Atlantique and the IRISA CNRS UMR 6074 laboratory.

My research activities concern the formal verification using the Coq proof assistant of program transformations and semantic properties of programming languages, such as those found in the CompCert C compiler and the Verasco static analyzer.

I teach mechanized semantics (in Coq), functional programming, formal methods (using the Why3 tool), and software vulnerabilities.

Member of Section 6 of the national committee for scientific research CoNRS from Sept. 2016.

Former coordinator of the LTP (Languages, Types, Proofs) group of the French GDR GPL. This group is funded by CNRS and meets twice a year in a French city.

Previously in charge of the M2 SSI graduate curriculum dedicated to information system security (2009-2013), and of the research master in computer science (2013-2017).
