I am a mathematician working at the CNRS in Marseille, mostly in dynamical systems and topology. I am involved in mathematical outreach, with a particular interest in connecting scientific and artistic practices.
I am a co-founder of the association Vagabond Mathematics whose goal is to support artistic and social projects related to math. At the moment, I am working on a project of an exhibition МАТЕМАТИКА telling stories of ten women in mathematics in Russia.
You are very welcome to my regular cinema club called CinéMaths, at Comœdia in Lyon, put in place with the help of the Mathematics and Informatics House in Lyon (la MMI).
If you are interested in some of my endeavours (research, outreach and/or art), subscribe to my newsletter (which is mostly in French and sporadically in English).

Here are some math community initiatives that I am proud to have been a part of.
Recreational mathematics seminar is a weekly seminar in the House of Mathematics and Informatics in Lyon MMI put in place by students for everybody, in order to speak simply about math, without pretension. I have created in 2014 and co-organized this seminar with many wonderful friends, such as M. Lhuissier, V. Borelli, V. Seigneur, A. Rivera and B. Sevennec. The seminar is still full of activity, and its organizers and format regularly change (even though, I heard, there still is cake before the seminar!).
Mai 12 is an international day of Celebration of Women in Mathematics that regroups initiatives all over the world. The tradition has been launched in 2019, and it has been very fun to be part of it since the start. Check out our beautiful site, and please participate in Spring of the upcoming year, with an event in your laboratory! Here is an article telling the first year adventure of May12.
N. Agarwal, C. Araujo, P. Bonfert-Taylor, M. Mahmoudi, M. F. Ouedraogo, O. Paris- Romaskevich, M.-F. Roy, E. Strickland, A. V. Gajardo May 12: Celebrating Women in Mathematics, From One Idea to One Hundred Events, Notices of AMS, journal version (2019)
Here is a list of my preprints and publications, with when possible links to videos of talks and slides. The by default language is English.

I had a chance to work on my PhD under supervision of Étienne Ghys and Yulij Ilyashenko, between Russia and France. I have defended my thesis twice (certainly, in order to understand it better) in 2016, in Moscow and in Lyon in order to become кандидат наук and docteur en mathématiques.
Always happy to see my coauthors
All my articles and preprints go to arxiv.
Here is the up-to-date (July 2021) version of my CV in French.
