🚨🚨🚨 NetSci Hackathon PSA!!!

Are you at NetSci this year? Wanna come a day early and hack on a cool new dataset? Join our hackathon which will take place on May 31.

We have limited space, so please indicate your interest through our application form by Mar 13: www.philchodrow.prof/higher-order...

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".

Statistical Inference for Network Models A NetSci 2026 Satellite Symposium

Interested in giving a talk at @netsciconf.bsky.social but missed the main conference deadline? Submit your work to the Statistical Inference for Network Models (SINM) satellite! Send your one page abstract by March 15 and check out sinm.network for more details!

How complex should network models be?

🚨 In our latest paper we quantify (if and) when higher-order interactions are informative versus reducible to pairwise structure without losing functional signal (e.g., diffusion behavior).

I believe science is much more like art than many scientists are willing to consider. I have a feeling that it would free us to do better science if we embraced this view. I may be mistaken but that's where I am mentally.

Phys. Rev. X: Fast Nonparametric Inference of Network Backbones for Weighted Graph Sparsification
http://link.aps.org/doi/10.1103/4pg6-mtmt

Excited to see this out! If you need to identify a network backbone but don’t know how to choose the number of edges to keep, here’s a Bayesian solution.

Are you from the US and would like to work as a postdoc in Austria, maybe in our lab? 25 new fellowships will be available in July from the @oeaw.bsky.social: www.oeaw.ac.at/en/news/25-n...

If you are interested; get in touch!

Nowadays, saying your lab is not doing AI (for something, or applied to something) is a revolutionary act.

The 2025 Euler Award in Network Science goes to Ginestra Bianconi! @gin-bianconi.bsky.social 👏

The Erdős-Rényi Prize in Network Science is awarded to Federico Battiston! ⭐

a thing I’ve noticed in my time in research: many people really want to believe that Data™ is some sort of magical object that contains objective truth

but the thing is, just like everything else, data is _produced_ via processes and mechanisms that profoundly affect the shape of the data

Journal of Physics: Complexity is an emerging interdisciplinary journal focusing on all areas of complex systems and networks, run by the excellent @gin-bianconi.bsky.social and an editorial board of top researchers across different subfields.

I've been guest editing a focus issue for Journal of Physics: Complexity with @jgyou.bsky.social, @gcant.bsky.social, and Cate De Bacco on Statistical Inference and Machine Learning for Complex Networks. See iopscience.iop.org/collections/..., and feel free to get in touch with any questions!

Finished reviewing my pile of papers for a premier data mining CS conference today and then read their other reviews. Wow. They are utter garbage: largely superficial, thoughtless, and vague. We should be ashamed to call this #peerreview and inflict this misery on each other and on our trainees 1/2
