I am a Postdoctoral Researcher at the University of Waterloo under the supervision of Prof. Shane McIntosh in The Software REBELs group.

I completed a Ph.D. in Computer Science from the University of Rennes under the supervision of Prof. Mathieu Acher (INSA Rennes), Dr. Djamel Eddine Khelladi (CNRS) and Dr. Olivier Zendra (Inria). During my Ph.D., I was a member of the the DiverSE research group at IRISA.

I hold a M.Sc. in Computer Science from the University of Rennes, while I was a student at ENS Rennes. I hold a B.Sc. in Computer Science from the University of Lille.
