I am a mathematician working at CNRS and in Mathematics Institute in Marseille, my area is dynamical systems. I co-organize a Rauzy seminar (subscribe to our newsletter and come to Zoom talks!) and the girls only math school Cigales, in CIRM, two times per year.I am involved in mathematical outreach, surfing on the frontier between science and art. I co-founded the association Vagabond Mathematics supporting art and society math projects. Our on-going project #streetmath is devoted to regularly drawing mathematical art in the streets of Lyon, you can support us on this donation page.I love to learn and practice storytelling in any form, with a high preference to moviemaking. My last (and postponed for some time) project is a trip and blog МАТЕМАТИКА telling stories of ten women in mathematics in Russia. Now I am working on a documentary film about girls in mathematics... to come in April 2023!I am a member of SNCS (National syndicate of researchers) and of No fly climate sci. I limit my plane travel as much as I can. The last time I flew a plane was 21st September 2021. I am a member of Femmes et mathématiques because I believe that mathematical community should be inclusive and welcoming to everybody who aspires for knowledge, curiosity and creativity.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 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.

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.
My (very smart!) coauthors
All my articles and preprints go to arxiv.
