I am currently a post-doc at IRMAR in University of Rennes I.
I’m mainly interested in the study of asymptotic behavior of dynamical systems and all the rich mathematics one can come across while working on this kind of questions : integrable systems, ergodic theory, foliation theory and geometry.
My goal is to explore and to share the joy of exploring with others.

My research turns around dynamics and geometry, and is often inspired by some "real world" physical systems. Currently I am interested in the study of maximally superintegrable systems.

My thesis was written under supervision of Étienne Ghys and Yulij Ilyashenko, in-between Russia and France. This great experience is called thèse en co-tutelle in French. I had two defenses in 2016: on the 25th of October in Russia and on the 7th December in France.
I am кандидат наук and docteur en mathématiques.
Please contact me if you are interested in a complete .pdf version of my thesis (available in English with French introduction as well as in Russian).

I have some teaching assistant experience accumulated (in Russian and in French). I taught courses in Higher School of Economics (HSE) in Moscow while I was a graduate student as well as at ENS de Lyon as ATER. I also organised some number of lectures and courses for motivated students. I co-organised a dynamical systems seminar at Moscow State University (MSU) when I was a graduate student and I taught some courses at the Summer School Modern Mathematics that takes place each year in Dubna, Russia.
