#### About

After a PhD under the direction of Alain Trouvé at the ENS Paris-Saclay, I am currently doing a PostDoc at Imperial College London in the team of Michael Bronstein. Starting from December 2021, I will join the new HeKA INRIA team in Paris as a Chargé de Recherche (permanent scientist position). Here is a short CV.

I am primarily interested in **geometry** - from computer graphics to Riemannian manifold embeddings. My main research interests are:

**Computational anatomy**: shape analysis for medical imaging and biology.**Optimal transport theory**: generalized sorting algorithms in dimension D > 1.**Geometric data analysis**: graph- and measure-theoretic methods to study large datasets.

#### July 2020: Geometric data analyis, beyond convolutions

I defended my PhD thesis on July 2nd, 2020: a related video recording is available here. My thesis is the most comprehensive reference on my work: it is written as an introductory textbook for data sciences and shape analysis, from a geometric perspective. If you just saw one of my talks on symbolic matrices, geometric learning and large-scale optimal transport, here is what you are looking for: KeOps library, GeomLoss package, Slides for the defense, PhD thesis.

#### Miscellaneous

My wife Anna is doing inspiring work on 3D shape textures. Check it out!

I played the flute for 11 years at the Conservatoire Paul Dukas, in Paris. I especially enjoy playing baroque music: J.S. & C.P.E. Bach, J.J. Quantz, G.P. Telemann... In june 2014, I gratuated from the Conservatoire, obtaining a "Certificat de Fin d'Études Musicales" diploma. Here is my leaflet programme, in French: Mathematics in Music.

My other interests include ancient history, Chinese culture and pedagogy. Here are some books that I would strongly recommend:

- Oliver Byrne's "Elements of Euclid": a pedagogical masterpiece.
- Thucydide's history of the Peloponnesian war, a thrilling mix of adventure and reflection.
- Chaos and Dimensions, two movies by Jos Leys, Aurélien Alvarez and Étienne Ghys. A must-see for anyone interested in math!
- Faraday's chemical history of a candle, explained by Bill Hammack, the engineerguy.
- Branch Education's YouTube channel. Clear, concise and illuminating videos on the inner workings of modern hardware.
- Topology from the differentiable viewpoint by John Milnor: a concise and elegant introduction to differential topology. Everything — including Brouwer fixed point theorem and Hopf theorem — is deduced from the single fact that a smooth and compact 1-manifold has an even number of extremal points!
- Hyperbolic geometry by J.W. Cannon: includes a proof of the usual properties of the Poincaré half-plane... without a single calculation, but stereographic projections and symmetries instead.
