I'm professor of computer science at UCLouvain in the ICTeam Institute. I'm also part of the Artificial Intelligence and AlgorithmsTwitter research group.


I obtained my Ph.D. from the UCLouvain University in 2009. I spent 5 months at Brown University. Then I joined the Dynadec startup to work on Comet during two years before working two more years at N-SIDE. I'm now at UCLouvain since September 2012.
