Filamentous growth everywhere! It is really fascinating that no matter if you are the fungus that grows as a "mold" in bread or on decomposing wood, in very unrelated lineages; the trademark is filamentous network growth!

Nat. Rev. Phys.: Collective dynamics on higher-order networks
https://www.nature.com/articles/s42254-025-00916-3

What's new since the first preprint version?

- analytical solutions for the case of hyperrings
- many more datasets: now 60, available through @xgi.bsky.social
- randomization procedures to test the effect of structural properties

Go check them out!

We use a cost function based on information theory and diffusion processes.

In brief, some empirical systems require higher-order structure, but pairwise models are sufficient for some others.

When should we favour a model with higher-order interactions over classical pairwise ones?

"Reducibility of higher-order networks from dynamics" is now out in @natcomms.nature.com

The final version of "Reducibility of higher-order networks from dynamics" is finally out in Nature Communications! 👇👇👇

Why does life explore so few of the forms it could possibly take? Using fractal descriptors, this #scienceadvances paper shows that Earth’s biosphere clusters around simple shapes, reflecting deep evolutionary constraints. @artemyte.bsky.social @manlius.bsky.social www.science.org/doi/pdf/10.1...

Group Science: The Open Source Study of Higher-order Networks With XGI | SIAM The CompleX Group Interactions (XGI) software package offers analytical tools, tutorials, and documentation for higher-order network science research.

We wrote a little something! @nwlandry.bsky.social and I talk about how new software to study networks with groups (like @xgi.bsky.social !) can help interdisciplinary collaborations tackle old questions from social ontology and the science of groups.

You can already accept all tracked changes of selected text! So just need to select all :)

One week left to apply to the UVA Biology PhD program! If you or someone you know are interested in contagion from a complex systems perspective, please reach out! I'm looking for a grad student! bio.as.virginia.edu/how-apply-gr...

Lots of higher-order interactions at the joint @beyondtheedge.network and RUNES workshop at AMU in Marseille this week. Thanks to @alainbarrat.bsky.social and @lordgrilo.bsky.social!

Final week to apply for the 2026 SFI Complexity Postdoctoral Fellowships

If you're an early-career scholar and passionate about collaborative, transdisciplinary research beyond traditional departments, this is the postdoc fellowship for you.

Deadline: Oct 1, 2025

Come be my colleague! Happy to answer any questions about what it's like living in Charlottesville and being in the department.

🚨🚨 New preprint just dropped! In collaboration with @colltoaction.bsky.social, Cliff Joslyn, @fralotito.bsky.social, Audun Myers, Joshua Pickard, Brenda Praggastis, and Przemysław Szufel, we define a new data sharing standard for higher-order networks. arxiv.org/abs/2507.11520

Thrilled to finally share a huge piece of my PhD project!
Our paper “The Topological Architecture of Brain Identity” is now out on bioRxiv: biorxiv.org/content/10.1... 🧵 1/n

🧠 Want to understand how different higher-order methods compare in brain connectivity analysis?

Check out our new preprint — a fantastic collab with past & present NPL members @lordgrilo.bsky.social :

A thread🧵

@nwlandry.bsky.social fighting against vibes-based estimations of the convergence when sampling from the configuration model. Good content.

Bonus: @xgi.bsky.social viz

Our first keynote @marilyngatica.bsky.social opening TopoNets @netsciconf.bsky.social with higher-order interactions for neuroscience

Learning from @maximelca.bsky.social how to be nice to people in science 🤣🤣 @netplace.bsky.social @netsciconf.bsky.social

Flyer of panel on science as a craft at NetSci25

If you are at #NetSci25, join us at 1pm for our @netplace.bsky.social panel on the topic of "Science as a craft: Balancing career and skill progression", with panelists @asteixeira.bsky.social, @maximelca.bsky.social and @captainkirk1041.bsky.social

Tomorrow at lunch 👇👇👇

🎉 Very happy to announce Maxime Lucas @maximelca.bsky.social as our next panelist! Maxime is an FNRS Postdoc at the Namur Institute for Complex Systems & UCLouvain in Belgium. He is interested in dynamical systems, complex systems, networks, and their applications to life sciences.

Next week at @netsciconf.bsky.social -- it's time for another edition of TopoNets!
🗓️ June 3, 2025
📍 FPN Paarse Zaal

A great lineup, including keynote talks by @marilyngatica.bsky.social , Kwang-Il Goh, @captainkirk1041.bsky.social & Maria Pope
