Our paper Gray codes for Fibonacci q-decreasing words solved a conjecture of Ömer Eğecioğlua (Santa Barbara, California) and Vesna Iršič (Ljubljana, Slovenia) from their recently published paper Fibonacci-run graphs I: Basic properties (31 May 2021).

The combinatorial community is awesome! On March 24, 2021, Bin Han, Jianxi Mao, Jiang Zeng anounced the proof of our second conjecture from this paper. The first conjecture remains open.
Our lab LIB participated in art-science exhibition "Les Réseaunautes",

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.
Je suis Maître de Conférences.
Before, I studied mathematics and computer science at Siberian Altai State University, where Sergei Zhilin was a supervisor of my Master thesis. During my Master internship I worked together with Jacques Malenfant and Olga Melekhova from Paris 6 University. We showed how to apply Reinforcement Learning and Artificial Intelligence to Autonomic Resource Allocation in Clouds.
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 position at Université de Bourgogne where I conducted research in two fields:
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.
For two years, I was a member of R&D group at Page Up.
