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!

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!

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 :)

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).

👏🥳 '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 · May 22

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.

Vectorisation weightings for persistence diagrams were shown to be a computationally efficient alternative to multiparameter persistent homology. The methodology was validated on two annotated, multiplexed tissue datasets—lupus murine spleen and COVID-19-affected human lungs.

Perez et al introduce a novel visualisation method—persistence weighted death simplices (PWDS)—which maps topological features detected by persistent homology back to their locations in the original tissue data, enhancing interpretability
