What an exciting week at @netsciconf.bsky.social ! If you still have some curiosity left, stop by this afternoon. I'll be presenting, “Toward Fairness in Network Algorithms: Rankings by Biased Random Walks.” 📍 Where: Algorithms, Inference & Reconstruction 3 (Kendall Square) 🕰️ When: 5PM

Later today (3.45pm) I’ll be talking at the NSIA (network-science-ai.github.io/schedule.html) workshop of @netsciconf.bsky.social about (exciting!) work on the interplay between generalization and working memory limits. Come through!

Come join us!! 👇👇👇👇👇👇👇👇

There seems to be a broad perception across psychology and neuroscience that work shouldn't be "too technical" in order to reach the broadest possible audience. While I think we should strive for accessibility, I feel that this attitude can also be self-defeating: why are we dumbing down?

Come join us!! 👇👇👇👇👇👇👇👇

New PhD position open in the lab. Details here: t.co/HZ1BvpSuAB

Very good article what it would take for AI to have "agency" and self-preservation goals (w/ a few quotes from me). & I appreciate the reiterated debunking of the "GPT-4 on its own lied to a TaskRabbit worker to solve a captcha" story. www.quantamagazine.org/why-do-we-te...

As Giovanni Petri shared with #NGN, sperm whales and humans have more in common than we think. Their coordinated support during a calf’s birth shows survival has driven strong social ties, even beyond kin. news.northeastern.edu/2026/03/26/s... @lordgrilo.bsky.social @projectceti.bsky.social

The 𝙎𝙘𝙞𝙚𝙣𝙩𝙞𝙛𝙞𝙘 𝙍𝙚𝙥𝙤𝙧𝙩𝙨 study dives into the acoustic side of a sperm whale birth 🐋, analyzing clicks and codas to reveal distinct vocal shifts during labor, birth, and early interactions, offering rare evidence of coordinated, non-kin birth assistance in the wild. tinyurl.com/m3pshz8y

Interesting piece — raises important questions about what higher-order formalisms actually buy us. Half-jokingly, it would make great panel material @netsciconf.bsky.social à la Leipzig dispute :) (Also, first commentaries are already coming out: lnkd.in/d8_nunck)

Renormalization in the brain? With @andreasantoro.bsky.social and @jesseba.bsky.social we're organizing a workshop at @cosynemeeting.bsky.social (Lisbon, March 16) on how coarse-graining principles from physics can explain neural computation across scales. nplresearch.github.io/neurorenorm2...

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. skewed.de/lab/posts/co...

Our review on multilayer network science is out on the arXiv. Thanks to all collaborators of the AccelNet MultiNet project, great working with you all 🙏 @alexvespi.bsky.social @ymoreno.bsky.social @lordgrilo.bsky.social @anduviera.bsky.social @baronca.bsky.social arxiv.org/abs/2511.23371

How do brain areas control each other? 🧠🎛️ ✨In our NeurIPS 2025 Spotlight paper, we introduce a data-driven framework to answer this question using deep learning, nonlinear control, and differential geometry.🧵⬇️

Is criticality a unified setpoint of brain function? Neuron www.cell.com/neuron/fullt... #neuroskyence

If you’re curious about how the shape of brain networks encodes identity and information, take a look at the full paper here: biorxiv.org/content/10.1... 10/n

This balance between redundancy and synergy, woven into each person’s unique topological scaffold, may offer a new lens on individual variability, and a powerful pathway for identifying cognitive or clinical biomarkers. 9/n

Third: most intriguingly, we found that the scaffold's structure dictates its information flow. The borders of loops handle redundant information, while the connections spanning these loops exhibit high synergy. It's a beautiful metaphor: integration happens within the voids. 8/n

Second, while FC fingerprints often draw from features confined to particular brain networks, scaffolds gain their power from inter-network connections. In other words, identity seems to live in how different large-scale brain systems interact 7/n

First, scaffold-based fingerprints achieved near-perfect identification accuracy (~100%), outperforming FC-based methods (~90%). Even more 🤯, they remained robust across different preprocessing strategies, brain atlases, and dramatically shortened scan times. 6/n

We tested this approach on resting-state fMRI data from 100 unrelated individuals in the Human Connectome Project. The results were striking. 5/n

To better capture this richer structure, we use homological scaffolds. Picture incrementally building a brain network by adding connections in order of strength. As we do this, loops begin to form. The scaffold is made of all edges that participate in these mesoscale loops 4/n

Traditional approaches to brain fingerprinting typically rely on Functional Connectivity (FC), which measures pairwise correlations between brain regions. But brains don’t just operate in pairs—networks of regions interact in complex, higher-order ways that FC often misses. 3/n

We show that the topological structure of brain connectivity—, homological scaffolds—offers a powerful and highly robust way to identify individuals based on their functional brain organization. 2/n

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
