During my Master internship I studied Reinforcement Learning and Artificial Intelligence together with Jacques Malenfant and Olga Melekhova from Paris 6 University. I defended my PhD thesis on December 2014 in Paris, under the supervision of Clémence Magnien. My Phd thesis is about the study of the Internet topology dynamics from network theoretical and statistical points of view. Then, I had a temporary teaching and research postion at Université de Bourgogne where I conducted research in two fields:

Currently I’m working in R&D group of Page Up, in Dijon. I teach Unix and Advanced Information Systems at ESIREM and continue the resarch in combinatorics and network science at Université de Bourgogne.


More than 700 hours of various CS courses. Find details here.


10 International Journals articles and 7 Peer-Reviewed International Conferences. See my publications page for details.
