Alison Pouplin

Hi there!

I am a researcher in the MLR team at Bayer, where I work on uncertainty quantification.

Before joining Bayer, I did a short postdoc at Aalto University with Vikas Garg and Markus Heinonen. And before that, I was lucky to do my PhD on a topic I still love the most: differential geometry in machine learning, supervised by Søren Hauberg and Georgios Arvanitidis. You can read my thesis here.

Even though I am now in industry, I stay very much connected to the academic world, with ongoing collaborations and workshops (GRaM 2024, TAG-DS 2025, GRaM 2026).

Oh, and I am a huge information-geometry nerd. I fell down that rabbit hole after reading Frank Nielsen’s work back in 2018 and never really climbed back out. If you somehow ended up here, and feel like nerding out, please say hi! I am sometimes in Berlin, Nantes, Copenhagen, Amsterdam and London.

GRaM 2026 at ICLR — our second edition! Proceedings coming soon.

10 Mar 2026 paper

On the Fisher Geometry of Diffusion Models’ Latent Space accepted as a poster at ICLR GRaM 2026. Led by Maria, a lovely follow-up to Rafał’s spacetime paper.

26 Jan 2026 paper

ICLR accepted two papers: The Spacetime of Diffusion Models: An Information Geometry Perspective (Oral) and Riemannian Variational Flow Matching for Material and Protein Design (Poster). A pleasure to work with the brilliant Rafał, Olga and Floor ♥

23 Dec 2025 workshop

GRaM got accepted as a workshop at ICLR, our second edition! We have a call for proceedings, tiny papers, blogposts and a competition coming soon.

9 Sep 2025 talk

Gave a talk at GPSS on Links between Riemannian geometry and Gaussian Processes. Thank you Carl Henrik Ek and Mauricio Alvarez for the invitation!

1 Jun 2025 news

Started at Bayer in the MLR team, working on uncertainty quantification, BO and AL for small molecules and FEP prediction.

9 May 2025 workshop

End of the wonderful workshop on Geometry for statistics and AI, in the beautiful Metochi Study Center. Thank you Libby Baker, Stefan Sommer and Erlend Grong, for the invitations. We had so many exciting discussions and… wine. :)

18 Apr 2025 talk

Gave a talk at the “Geometry and Information” seminar at HSE, organized by Maxim Beketov. Loved the Saint Petersburg Mathematicians and Their Discoveries book gift.

24 Oct 2024 news

First run of our Geometric Deep Learning course at Aalto! Created together with Caglar Hizli, Katsiaryna Haitsiukevich and Erik Schultheis. So many lovely and smart students!

29 Jul 2024 workshop

GRaM 2024 at ICML, organised with the amazing Sharv. Proceedings published in PMLR.

1 Feb 2024 news

26 Oct 2023 news

PhD defence day — extremely nervous, but so lucky to have the most amazing examiners: Frank Nielsen, Michael Bronstein and Mikkel N. Schmidt. And the most incredibly supportive mentors and PI ever: Søren Hauberg, Georgios Arvanitidis and Carl Henrik Ek. ♥

23 Feb 2023 talk

Gave a talk at TAG-DS on Finsler geometry — see the paper.

Jun 2022 workshop

Organised the Hitchhiker’s Guide to Complex Geometry reading group with the wonderful Pablo A. Morales (Araya Research) and Challenger Mishra (Cambridge University).

1 Jan 2022 news

Started a 3-month internship at Relation Therapeutics. Together with Thomas, Alice, and Paul, we built PyRelationAL, a Python active learning library. I wished I could have stayed longer, but ERC funding restrictions prevented me from extending my PhD…

Oct 2020 workshop

Co-organised CogSys ML Talks at DTU with Federico Bergamin: a seminar series on machine learning and applied mathematics. Lovely community building during covid, and some speakers ended up working together. :)

1 Mar 2020 news

Start of my academic journey and my PhD… with the amazing Søren Hauberg at DTU. ♥
