Ever wondered how to quantify the spatial relationship between different species (eg cell co/trilocalisation)? Lovely working with this interdisciplinary team — math @nerdarajan.bsky.social @tomchaplin.xyz @majirouses.bsky.social meets oncology @leedham-simon.bsky.social @joshuabull.bsky.social

Nikola Sadovek in @haharrington.bsky.social group & Daniel McGinnis @princetonupress.bsky.social, solved a 38-year-old mathematical puzzle by finding a precise rule for when a point, line, or plane can simultaneously intersect a whole family of convex shapes. www.sciencedirect.com/science/arti...

Come and join our Discrete Laplacian workshop in Dresden, Germany 🙌!

With Karel Devriendt, Otto Sumray, and Giulio Zucal, we are organising the workshop in MPI-CBG, 22-25 Jun 2026.
Thanks to the support from Heather Harrington's group at CSBD, MPI!

Abstract ddl: 1 Mar 2026

Very grateful to work w/ @yutian.bsky.social @hirokisayama.bsky.social Renaud Lambiotte for this foundational work! It made us rethink what constitutes a "unit" of interaction, leading to the idea that grouped coherent edges can form a single interaction (matrices). Hope this brings a new angle 🙂.

Two years today! Very grateful 🙏 @mpi-cbg.de @csbdresden.bsky.social @math-mpicbg.bsky.social

Come fly with us, let's fly, let's fly away.

We are searching for an AI researcher in lab automation, statistical ML and (theoretical) physics AI for bio/med. Expression of interest and nominations welcome!!!

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.

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.

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

The group of Meritxell Huch @merihuchlab.bsky.social together with the Heather Harrington group @math-mpicbg.bsky.social & @oxfordmathematics.bsky.social develop next-generation organoid model that reconstructs liver architecture to better understand liver disease. www.mpi-cbg.de/news-outreac...

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).
