Lior Pachter @lpachter.bsky.social from CalTech visited us this week - a real interdisciplinarian, spanning fields from algebraic statistics & geometry to computational biology. Here he is highlighting the confounding of biological signal & technical noise in single cell genomics data. @mpi-cbg.de

New preprint: We study Lotka-Volterra ecological dynamics through computational algebraic geometry. By encoding feasibility & stability on the real Grassmannian, we prove certain ecological networks are mathematically impossible 🧮🌿 arxiv.org/abs/2509.00165

Also from Oxford and the @haharrington.bsky.social ASB group is Rob McDonald. He models spatial data in many contexts - think tumours, Covid, and climate change. Wonderful to have you here too Rob!

The wonderful Gill Grindstaff has been with us this week from Oxford, working on a couple of phylogenetic protects with @haharrington.bsky.social and Rene Hoekzema. Welcome Gill!

New pre-print: Probabilistic algorithm for computing all local minimizers of Morse functions on a compact domain - Archive ouverte HAL 📄 Preprint: hal.science/hal-05160251v1 💻 Julia: github.com/gescholt/Glo... #Optimization #JuliaLang #ScientificComputing #ComputerAlgebra

Silviana Amethyst from our ASB group is teaching the Computational Algebraic Geometry course at the Gene Golub #SIAM summer school in Montréal (August 4-15th: www.siam.org/programs-ini...). Topics: foundations of, software of, & advances & open problems in computational algebraic geometry 😊. Enjoy!

Thanks to @aidadoesmath.bsky.social and Max Wiesmann for organising this Dresden-Leipzig meetup! And for the MTO at @mpi-cbg.de for this beautiful picture of all the attendees.

A great short chalk talk on game theory from Irem Portakal from MPI-MiS.

A couple of beautiful short talks from PhD students Elke Neuhaus from MPI-MiS on quantum chemistry, and Leon Renkin @leon-renkin.bsky.social from MPI-CBG on persistent homology in organoids.

We had a couple of short talks over lunch, including one from Niharika Chakrabarty Paul from MPI-MiS, about computing phylogenetic invariants for time-reversible models, from a paper (arxiv.org/abs/2505.20526) that started at the Women in Algebraic Statistics workshop in Oxford last year :)

Eric Pichon-Pharabod from the Numerical Algebraic Geometry group at MPI-MiS is now talking on algebraic curves.

And now Ben Hollering - a Humboldt postdoc from TU Munich and long term guest of MPI-MiS in Leipzig - is telling us about graphical continuous Lyapunov models

Next up was Carl Modes, leader of the Network Complexity and Systems Biophysics group here at @mpi-cbg.de and @csbdresden.bsky.social, talking about the theoretical underpinnings of morphogenesis: topology and geometry meeting biology.

Awesome new paper in @nature.com from PhD student Benjamin Yang @benjaminojr.bsky.social from the Algebraic Systems Biology Group!

Haochen Yang@benjaminojr.bsky.social · last yr.

New interdisciplinary math+bio paper! Mouse liver assembloids model periportal architecture and biliary fibrosis. In vitro assembloids modelling the mouse liver periportal region were built to study processes causing scarring (cholestatic injury/biliary fibrosis) and the shape change this causes.

I posted about this paper this a while ago on another website, but figured I'd post it here now that I have a few followers. (Joint with @haharrington.bsky.social, Jacob Leygonie, @uzulim.bsky.social, and Louis Theran). arxiv.org/abs/2411.08201 1/10

We did it! 🎉 🍾🥂 Our Excellence Cluster Physics of Life (PoL) got renewed until 2032! I am so proud of our team and all the great work we did to achieve this.

Physics of Life Dresden@poldresden.bsky.social · last yr.

We're thrilled to announce that our Excellence Cluster Physics of Life (PoL) has been renewed for a second funding phase (2026-2032) by @dfg.de ! Thanks to everyone who made this possible! 🎉👏 We'll continue our cutting-edge research towards understanding what brings matter to life! #biophysics #dfg

👏🥳 'Funding the Cluster of Excellence Physics of Life for its next phase represents an outstanding opportunity to bring cutting-edge research at PoL to a new level. PoL will use its unique perspective to understand key features of living systems, including the emergence of function and robustness.'

TU Dresden@tudresden.bsky.social · last yr.

Outstanding success: 🎉 #TUDresden shines with 5 Clusters of Excellence. @dfg.de & @wissenschaftsrat.de announced that decision today. TUD has impressively proven its claim to be a top university for the 21st century. ℹ️ tu-dresden.de/tu-dresden/n...

New paper on arXiv! 'Topology across scales on heterogeneous cell data', From Maria Torras Perez, @torrasperez.bsky.social, Heather Harrington @haharrington.bsky.social, et al: arxiv.org/abs/2505.02717

Topology across Scales on Heterogeneous Cell Data

Multiplexed imaging allows multiple cell types to be simultaneously visualised in a single tissue sample, generating unprecedented amounts of spatially-resolved, biological data. In topological data a...

Talks, discussions, great dinners, and even some Mathletics (thanks Hannah and Tessa!). A wonderful retreat.

We had many others too, but here’s us celebrating Maria Torras Pérez’s @torrasperez.bsky.social new paper going up on arXiv about a new visualisation method to study spatial patterns in cell distribution data. More to come on this!

Sergio Serrano de Haro Iváñez @sergiosdhi.bsky.social from the Algebraic Systems Biology group explaining how topological data analysis can be applied to colorectal cancer.

Joining us at the retreat, and soon also as a postdoc in @aidadoesmath.bsky.social’s group is Carlotta Langer talking about information-theoretic complexity measures in the context of integrated information theory. Madly interesting stuff.

Karel Devriendt, a postdoc with @turkuozlumcelik.bsky.social in the Mathematical Structures and Applications group, talking about his work on discretising curvature in graphs.
