I’m happy to share that, as of April 1st, I will be taking on a W3 Professorship in Complex Systems and Network Science at the Goethe University Frankfurt @goetheuni.bsky.social.

BeyondTheEdge Seminar Tiago Peixoto Tiago Peixoto in the BeyondTheEdge Seminar Series

Want to learn more about our recent work disentangling the conflation between hypergraphs and higher-order interactions?

I will be giving a @beyondtheedge.network seminar March 16, 2026 3:00 PM CET.

Paper: arxiv.org/abs/2602.16937

Zoom link here: www.beyondtheedge.network/event/semina...

New blog post:

"Higher orders need higher standards"

I discuss our current work disentangling misconceptions around "higher-order" networks: arxiv.org/abs/2602.16937

Explainer thread for the paper here: bsky.app/profile/tiag...

Graphs are maximally expressive for higher-order interactions We demonstrate that graph-based models are fully capable of representing higher-order interactions, and have a long history of being used for precisely this purpose. This stands in contrast to a commo...

New on the arxiv:

“Graphs are maximally expressive for higher-order interactions”

arxiv.org/abs/2602.16937

We clarify central misconceptions in the recent literature on "higher-order networks".

Explainer 🧵: 1/N

The perplexing “connected cluster axiom” – Inverse Complexity Lab Research group on inverse problems in complex systems and network science.

I wrote a blog post about the often stated but never explained assumption that communities in graphs should always be connected.

This is inconsistent with statistical significance and null models that underlie the most widely employed methods.

A couple of weeks ago we had our first “Complexity Lab Retreat” at great location in Traunkirchen!

We had the opportunity to flex our methodological muscles and learn the dark secrets of the C++ internals of @graph-tool.skewed.de! 💀🤘

There will be more of these!

Any interest of participation from outside the group? 🤔

🚨 New paper on ArXiv:

“Uncertainty quantification and posterior sampling for network reconstruction”

TL;DR; We present an efficient method to sample the entire ensemble of possible network reconstructions that are compatible with an indirect observation, e.g. a dynamics.
