Higher-order interactions shape collective human behaviour Nature Human Behaviour - Battiston et al. discuss the emerging paradigm of higher-order network science and its applications to social systems and human dynamics.

Our perspective piece (and one of my last chapters of the PhD thesis) was published in Nature Human Behaviour. We review the literature on how group interactions shape collective behaviour and highlight cases where they are (or are not) important to consider. (link: rdcu.be/eU5jC)

I have started as a Postdoctoral researcher in the Department of Evolutionary Anthropology at University of Zurich with Andrea Migliano and Lucio Vinicius. I will be analyzing social networks in hunter-gatherer populations and other great apes populations. It has been a fun few months so far!

2/5

Many personal things have happened in the past few months and it is time to update the social media!

I received my PhD in Network Science at @ceu-dnds.bsky.social under the supervision of @fede7j.bsky.social after a wonderful 4 years in Vienna with amazing friends and colleagues!

The Structure of Psychopathology on Reddit: Network Analysis of Mental Health Communities in Relation to the ICD Diagnostic System Background: Social media platforms such as Reddit have become important spaces where individuals articulate their distress, seek support, and explore alternative ways of understanding mental health ou...

What does psychopathology look like from the perspective of people seeking support? Network analysis of Reddit communities vs diagnostic criteria.

🎓 Yesterday, January 21, 2026, Júlia Számely successfully defended her PhD dissertation on misinformation engagement, combining survey data with digital trace data to better understand who engages with misinformation online—and why.

Congratulations! 🎉📚

Do you REALLY need anything else to be convinced?
We didn’t think so.

Fourth-year PhD student @claraeminente.bsky.social presented new work on two fronts: why people overestimate the size of racial minority groups in the US, and how intersectional homophily might reduce racial segregation in school friendship networks. 👏

#WeAreCEU #NetworkScience

4th-year PhD candidate Helcio Felippe presented new work on using information theory to summarize network structure — including a measure of network & hypergraph similarity and a principled way to reduce higher-order representations. 👏

#NetworkScience

On Dec 3, 4th-year PhD candidate Martí Medina-Hernández presented how ML and network science can reveal hidden patterns of corruption across Mexico, Bulgaria & Italy.

His work shows how data-driven methods can support stronger public-integrity policy.

#WeAreCEU #NetworkScience #CorruptionResearch

On Dec 3, 4th-year PhD candidate @loreb92.bsky.social presented his research on group dynamics in human & animal systems.

His work shows how leadership shifts affect software teams, how bird groups form stable higher-order social cores, and how to detect such structures from data.

#NetworkScience

3rd-year PhD student @bojanevkoski.bsky.social presented new work on mapping the structure of psychopathology using large-scale, heterogeneous data.

He compared insights from online support communities with clinical and registry data to uncover patterns that may inform future diagnostics.

Structural Reducibility of Hypergraphs An information-theoretic framework finds and removes redundancies in a hypergraph representation of a network, allowing for more efficient analysis of higher-order elements.

Animal interactions are not dyadic as usually modeled, so how relevant are higher-order relationships? The first part of #CRAB ends with Lorenzo Betti modelling biological behavior beyond pairwise interactions, uncovering higher-order structure within cohesive groups.
