Olga Paris-romaskevich
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 GALS. Starting 1st October 2024, I will work in Institut Camille Jordan in Lyon.I tell stories and create artistic performances. 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 women in mathematics МАТЕМАТИКА. 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 am interested in questioning the way we make a community in mathematics and in science. I am a member of European Mathematical Society Outreach and Engagement Committee and an elected member of the scientific council of the mathematics institute of CNRS, CSI de l'INSMI. I am very proud to be part of scientific council of IMéRA.
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).
I do not accept any new "girls and math/women and math" meetings till the end of this academic year.
I said yes to enough, and my calendar is full!

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.

Here are the initiatives that I am proud to have been a part of.
Recreational mathematics seminar in LYON (OR la détente)
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 and professors discussing math together. And it worked quite well! The seminar is still ongoing (it has 10 years!), check out their Facebook page.
May 12: Celebrating Women in Mathematics
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.

Science and 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.
Programmation Bobines de Sciences 2024/2025 est prête !
Tous les RDVs ont lieu samedis matin, à 11h, au cinéma Comoedia. Pour voir les films et notez les dates, RDV sur la page des Bobines du site de la MMI. Première rencontre aura lieu le 2 novembre 2024 autour du film Mécanique des choses.
My cinema work
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
2023 Alicia Boole aux pays des polytopes (script writer, co-written with director Denis van Waerbaeke) for Season 2 of Voyages
2023 La toupie de Kowalevksaïa ou la meilleure façon de tourner (script writer, co-written with director Denis van Waerbaeke) : watch on ARTE or on Youtube for S2 of Voyages
2023 La théorie du chaos (scientific council) : watch on ARTE or on Youtube for S2 of Voyages
2023 Loi de Hardy-Weinberg (script writer, co-written with director Cassia Sakarovitch), for the series Grande Aventure des Mathématiques for Lumni
I also work on cinema projects 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 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.
Upcoming events
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!
