Here is the Book! Popular exposition of the brain neurobiology with illustrations by Yulia Kirgizova.



I have an open one-year postdoc position in combinatorics. It is about study of patterns and pattern correspondences between different combinatorial structures: permutations, lattice paths, trees, words, RNA structures, &c. Usually, we are working with structural equations, bijections, generating functions, asymptotics, combinatorial statistics. We also plan to study real bioinformatic data that reflects primary and secondary RNA structures.

Candidates with experience in these (combinatorics, bio-informatics) or related areas will be considered. Please contact me by e-mail if you are interested. Applications will be reviewed on a rolling basis, until the position is filled

Financial support is provided by "ANR JCJC PICS : Patterns in Combinatorics" project. Salary estimation: INM 540, ≈ 2 600 € brut, ≈ 2 100 € net. There is also an end-of-contract indemnity: 10% of total brut.


I also have several intership positions for master students in combinatorics or bio-informatics. Please contact me by e-mail for details.


In July 2023 we organize Permutation patterns conference in Dijon.

Je suis Maître de Conférences.

I do combinatorics at LIB laboratory of Université de Bourgogne. My teaching include Unix, Information Systems and Big Data related courses at ESIREM.

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:

For two years, I was a member of R&D group at Page Up.
