Here, we introduce a topological approach that reframes physiological brain recordings as a time-varying geometric structure. By quantifying changes in its shape via persistent homology, we extract robust biomarkers that identify seizure onset and end in real time.

Mum, I'm famous! I am on the cover of Chaos.

When you organise a workshop in London this is the *Official* Conference Photo😂🍻 Thanks to all the speakers, presenters and participants of the last London-Oxford-Paris TDA Meeting! We look forward to seeing you at the next edition! :)

Open call for the poster session. Limited funding is available to support early career researchers.

The organisers : Omer Bobrowski (QMUL), Anthea Monod (Imperial), Ximena Fernandez (City), Vidit Nanda (Oxford).

📢 Registration open! Special edition London-Oxford-Paris TDA Seminar 🔗 6–7 Nov 2025 | City University of London Open to all researchers & students in algebraic topology, computational geometry & TDA 📅 Details & registration (deadline 24 October): sites.google.com/view/london-ox…

Happy to announce the Tube Neighbourhood Meeting – July 17 in London! A day of great talks on Topological Data Analysis, plus a celebration of my new appointment at @CityStGeorges. Info: sites.google.com/view/tubeneigh… Register (no fees, but limited spots): forms.gle/gvtzwFXZfjgAxT…

@Pseudomanifold @ERC_Research Massive congratulations Bastian! It’s almost HOLES GPT: Higher Order Learning of Essential Structures with Geometry, @Pseudomanifold and Topology

Friends, as the saying approximately goes: "Fortune favours the bald" 👴 👉 My proposal "HOLES: Higher-Order Learning of Essential Structures with Geometry and Topology" was successfully funded with a 1.5M € @ERC_Research Starting Grant! 👈 🤯🤯🤯 This will allow me to pursue my research in #geometry, #topology, and #MachineLearning! 🍩 I'm very excited, in particular after the great feedback by the reviewers! Attached is the picture of a happy and lucky PI! 😁 Having moved to @unifr 🇨🇭 recently, I'm grateful that @SBFI_CH has options for funding even though Switzerland was a nonaffiliated country when I wrote this grant last year (with a baby 👶 on my lap, no less). (it's a shame that 🇪🇺 and 🇨🇭 did not arrive at an agreement that covers submitted grants, but I hear the negotiations are going well otherwise) 🚨 Again, I'm hiring soon at all levels, so please share this widely! 🚨

This is how a proper research dinner goes in Nagoya 🇯🇵

@vh_wes Exactly that!

@pi_ene I can only imagine the feeling of pride and joy!!!

It’s happening!

@RaphalHOAREAU1 @caeater_7306 Will definitely take a look on that. Thanks for pointing it out!

@pi_ene @caeater_7306 But they work on dark matter and dark energy which have predicted nothing nor explained anything so far. Whereas the maths of the bimetric manifolds have yet to be described.

@RaphalHOAREAU1 @caeater_7306 Sounds fascinating! Indeed I recently travelled to Nagoya 🇯🇵 to collaborate with the cosmology research group at the University.

@pi_ene @caeater_7306 Could you get involved in the mathematics of the Janus Cosmological Model? That model deals with manifolds with two metrics.

@celsius Thanks! I can say it was a hard path to finally achieve it

@pi_ene I don't know you but I'm proud of you. Well done...

@pgroisma Gracias Patu!

@pi_ene Felicitaciones Xime!

@caeater_7306 Topology and geometry

@pi_ene what kind of math is that in your header?

@BanikGurudas Trust in the process, it is hard but it is also gorgeous when you finally understand it. It takes patience and a lot of effort. Good luck!

@pi_ene Congratulations professor 🥳🥳🥳 Any trip for the student like me... Who struggle with math but want to know it???
