About me

I am currently a post-doc researcher at Inria Nord Europe for the EU H2020 VESSEDIA project. Previously, I was a teaching and research assistant (ATER) at the university institute of technology of Orléans, associated to the Laboratoire d'Informatique Fondamentale d'Orléans (LIFO). I prepared my PhD at the Software Reliability Laboratory of the CEA LIST.

I am interested in the analysis of concurrent code using formal methods and more precisely proof.

Research

Currently, I am involved in the EU H2020 VESSEDIA project that aims at making formal methods easier to apply in the context of the internet-of-things where many security risks are rising as IoT devices are more and more widespread. My current work is to apply formal verification to the Contiki microkernel (an lightweight OS for IoT) and its libraries, mostly to show the absence of runtime errors. I mostly use Frama-C with the EVA plugin and the WP plugin.

In the context of Contiki, concurrency is only simulated using a library called protothread which allows cooperative multi-tasking without the need of multiple stacks.

My PhD thesis work is about a (formally correct) code and specification transformation from concurrent to equivalent sequential code. It allows one to verify a concurrent code using tools dedicated to sequential code. Such a transformation is valid under the assumption that the verified program has a sequentially consistent behavior. Our processors implements memory models that do not guarantee it. A part of my work is to study these models, and to define ways to analyze programs taking them in account.

Teaching

I am the author of a tutorial on Frama-C and WP.

I mainly teach code validation (using test and deductive proof), algorithms (basics, and then graphs and automaton), methods and languages for object-oriented design, and multi-core programmings (parallelism and concurrency).
