During my Master internship I studied Reinforcement Learning & Artificial Intelligence together with Jacques Malenfant and Olga Melekhova from Paris 6 University.
I defended my PhD thesis on December 2014 in under the supervision of Clémence Magnien (Paris 6 University). In my PhD thesis I have studied the Internet topology dynamics from network (graph) theoretical and statistical points of view.
Then, I had a temporary teaching and research postion at Université de Bourgogne (Dijon, France) where I did Discrete Mathematics (mostly Combinatorics) together with Jean-luc Baril, Armen Petrossian, and Vincent Vajnovszki. During this period I also worked in the areas of Social Network Analysis: together with Eric Leclercq, Marinette Savonnet, Nadine Cullot, Thierry Grison, Elisabeth Gavignet, Lobna Azaza, Ian Basaille, Alexander Frame and Tatiana Kondrashova we analysed massive amounts of tweeter’s data and its dynamics.
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.
Almost 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.

Our paper about reinforcement learning for autonomic resource allocation in clouds was re-presented by Muthu Karunarathna in series of students seminars organised by Eiko Yoneki in the Computer Laboratory, University of Cambridge. The original paper was presented at Seventh International Conference on Autonomic and Autonomous Systems, ICAS 2011 and received a Best Paper Award.
