I am a mathematician at CNRS. I work in the Mathematics Institute in Marseille, my area of interest is dynamical systems with motivations from physics. My current work concerns the dynamics of tiling billiards and the Novikov's conjecture about plane sections of triply periodic surfaces, inspired by physics of conductivity. My work is partially supported by the ANR (wonderful) GALS (ANR-23-CE40-0001).I am a storyteller. I have some experience in filmmaking such as editing, script writing and directing (both theater and cinema). I am the author of a blog about ten Russian female mathematicians МАТЕМАТИКА.I like spending time with people creating together. With the association Vagabond Mathematics, co-founded in 2020 with Marie Lhuissier, we draw the chalk art with us in the streets of Lyon.I believe in building utopias by collective action. I am part of SNCS (National syndicate of researchers), SMF (Société Mathématique de France) and femmes et mathématiques. I am a member of European Mathematical Society Outreach and Engagement Committee. I am an elected member of the scientific council of the mathematics institute of CNRS, CSI de l'INSMI. Last but not least, very proud to be a member of scientific council of IMéRA.
BIG NEWS : We have just finished writing a book ! It is called "Matheuses (Mathgirls)" about sociology of relationship with mathematics in France (with math problems in it that I have written!), co-written with Clémence Perronnet and Claire Marc. You can find it in French bookshops starting 25th January 2024.
If you are interested in some of my endeavours (research, outreach and art), subscribe to my newsletter! (which is mostly in French and sporadically in English).

The picture on the screen is made from a hill on Olkhon island, also called the heart of the lake Baikal. The picture of myself is a picture of a (Polaroid) picture made at Math and Art conference that I organized in CIRM in December 2023. I am playing with a top made by Ulysse Lacoste in a t-shirt Свободу всем! (Liberty to all, in Russian) demanding the liberty for political prisoners.Both are taken by Bertrand Paris-Romaskevich CC BY-SA.
Here are the initiatives that I am proud to have been a part of.
Recreational mathematics seminar (known as Séminaire de la détente) started as a weekly seminar in the House of Mathematics and Informatics in Lyon MMI. I have created it in 2014 and co-organized this seminar with M. Lhuissier, V. Borelli, V. Seigneur, A. Rivera, L. Mathis and B. Sevennec. My dream was to create the space of exchange between people interested in math in Lyon -- students, professors, anybody, that would be fun and not too snobbish. And it worked quite well!
The seminar is still ongoing, check out their Facebook page.
May 12 is an international day of Celebration of Women in Mathematics that regroups initiatives all over the world. The tradition has been launched by our international collective in 2019. Check out the site, and participate every year, with an event in your laboratory! Here the article presenting the adventure of May12.

I was a main organizer of the "Journée parité" of mathematical community in 2023, organized in ENS de Lyon. For more details on the meeting, see its webpage. The illustrations in live-sketching form were done by wonderful Lison Bernet all along the day. The next meeting will be organized in the Summer 2024, in Institut de Mathématiques de Marseille by Anne Pichon, Magalie Ochs, Peter Haïssinsky and myself. Here are some materials from these meetings :

Cinema club in Lyon -- Bobines de sciences
I organise a cinema-club CinéMaths (2018-23) and now Bobines de Sciences (2023+) as a collaboration with a House of Math and Informatics (MMI) and a cinema Comœdia. For me this ciné-club is an occasion to make a science a tool for democratic debate, and to watch good movies together. To come to Bobines de Sciences, please make a reservation (a couple of weeks before the date of the event) on the site of the cinema. You can also follow the program on the page of MMI.

My work for movies on math
I will be happy to be involved in the creative process of movie making (from scientific counsil to script writing to directing/co-directing, I have experience with all of this and love doing it).
2018 Je voudrais vous parler de mathématiques (co-directed with Coralie Gourdon). This movie was done in 48h and won a coup de cœur of the jury atPariScience2018 festival
2021 Pique-nique sur le plan complexe (scientific council), for Season 1 of Voyages aux pays des mathématiques (Voyages), directed by Denis van Waerbaeke
I can also do cinema not related to math and science!
Here are some of my personal filmic experiences : Ten trees, Une grue et une abeille and Poissons du Rhône. I also did several trailers for friendly theater companies in collaboration with Bertrand Paris-Romaskevich.At the moment, I am working as a chief translator on the project Knam - un théaêtre en Exil of Lionel Retornaz, telling a story of a theater that existed almost for 40 years at Komsomolsk-na-Amure and closed when Russian government started a full-scale war against Ukraine. All the actors left, and now live and work in Lyon.
Here are the research conferences we can meet each other, outreach activities in which I participate, as well as some artistic projects and events. Join me at Bobines de Sciences!

Matheuses : LES FILLES, AVENIR DES MATHÉMATIQUES :
the book is out in the wild!
Matheuses is a book (in French) about girls in mathematics, written in collaboration with a sociologist Clémence Perronnet and a science mediator Claire Marc. This project is born from the encounter between sociology and mathematics. From 2020 to 2023, I have been one of the organizers of a school for girls in mathematics called Cicadas in CIRM, Marseille. Clémence Perronnet, sociologist and specialist of social and gender inequality with respect to scientific culture, with her collaborator Alice Pavie, PhD student in sociology at the time, conducted a 2-week sociological observation study at our math school.
Presentation of the book.At 17 years old, 1 of 2 French school girls doesn't study math anymore (contrary to 1 of 4 boys).
Many questions arise from teachers, families, science professionals and adolescents.What can one do so that there are more girls in math? How to lead a class to support them? How to encourage your daughter to do math if you abandoned yourself How to change math practice so that it excludes less? Finally, how to feel less alone if one is a girl loving math?Our book is a book on math and a book of math, and it brings the largest possible answers to these questions, presenting a sociological study with voices of 45 adolescent girls about math, as well as proposes original math problems to discover at your pace.A book of research inviting to a research practice !

If you are interested in doing inclusive science (and in particular, math) outreach, and you read French, I recommend you the work of Clémence Perronnet to get you started thinking about how the scientific culture is constructed socially. The last link is the article presenting in more detail the Cicadas school and my thoughts about it.
