Welcome to my page!

I am a professor of computer science at the University of Geneva, head of the ALGO group. I am also affiliated with the LaBRI, University of Bordeaux, in the Combinatorics and Algorithms department.

Research interests: highly dynamic networks, temporal graph algorithms, computational complexity, distributed computing, and all kind of things interacting in a decentralized way (including security concerns).
