Now out: "Directionality-induced jamming in multiplex networks" (arxiv.org/abs/2510.22634). We uncover a previously unreported diffusion regime, termed directionality-induced jamming, in multiplex networks that arises solely from the directionality of interlayer couplings. (1/4)

Now out: "Rumor propagation on hypergraphs" (arxiv.org/abs/2504.19305). We propose a higher-order rumour model incorporating a group-based annihilation mechanism. We run computational experiments to characterise the model's dynamics in synthetic and real systems... 1/5

New MS: "Predicting the critical behavior of complex dynamic systems via learning the governing mechanisms" (arxiv.org/abs/2504.09622). We propose a framework to learn the rules that govern the dynamics of a system & apply it to study SIR dynamics & predict critical properties 1/3

Science, as well as technology, will in the near and in the farther future increasingly turn from problems of intensity, substance, and energy, to problems of structure, organization, information, and control. John von Neumann Well, we are already there ...

Join us for the inaugural BeyondTheEdge Seminar by Ginestra Bianconi (QMUL) on Thur, Jan 16 at 15h CET! More information at www.beyondtheedge.network/event/semina...

Very last paper of 2024 -never published a paper on Dec 31st. Kudos to my coauthors!

Last of 2024: "Interplay of epidemic spreading and vaccine uptake under complex social contagion"(arxiv.org/abs/2412.11766). Here we investigate the interaction between disease dynamics (simple contagion), and human behavior in vaccine uptake (complex contagion). Results show a rich phase space.

Research on higher-order network interactions and dynamics. Who is missing? go.bsky.app/KhJsLVo

Delighted to see our work (which I co-authored with @hfarruda.bsky.social and @ymoreno.bsky.social) getting additional media coverage, this time right ahead of Irish elections. www.breakingnews.ie/general-elec...

The 2M€ investment in upgrading & expanding our HPC facilities is essentially completed. We have got a quite state-of-the-art "Agustina" supercomputer unit, which will allow doing our usual complex systems research + plenty of new projects in the AI domain. Exciting times ahead!

A network science starter pack as of November 27, 2024 Please suggest additions! go.bsky.app/MWbwLHC

Thrilled to become the EiC of the Journal of Complex Networks @OxfordJournals. I will work to keep & span the journal's reach and impact on our #networkscience community. Thanks to my predecessor Ernesto Estrada for his excellent job. Please consider submitting your next work to JCN!

Now out: "Contagion dynamics on higher-order networks" (arxiv.org/abs/2402.14938). This is a focused review of the topic that also proposes a unified formalism covering most of the functional forms used for the spreading dynamics and discusses a roadmap for empirical validation.

Glad this work is now published, just before @Micovar_ public PhD dissertation! See the paper for + details of our findings. Main take-home: older adult vaccination can reduce TB incidence in China if the vaccine protects already exposed individuals. www.frontiersin.org/journals/pub...

Latest out: "Characterizing the role of human behavior in the effectiveness of contact-tracing applications" (frontiersin.org/articles/10.33…). Here, we developed a model that allows exploring the impact of human behavior on the effectiveness of digital contact tracing (DCT) systems (1/2)

I am visiting Guido Caldarelli at Ca'Foscari University these days and giving today a lecture to students on disease dynamics. I am lucky enough to get an autographed copy of Guido's book!

Just out "Robustness and complexity of directed and weighted metabolic hypergraphs" (arxiv.org/abs/2310.03623). We propose a new hypergraph-based representation of metabolic networks that captures HOI among metabolites and reactions, preserving all essential information.

Just out "Model-based impact evaluation of new tuberculosis vaccines in aging populations under different modeling scenarios: the case of China" (medrxiv.org/content/10.110…). Main conclusion: elder vaccination is a suitable option to reduce the incidence of TB in China.

An exciting new PhD project is available in my group to work on synergistic coevolution. The project will analyse an experiment, in which a cooperative interaction evolved between two bacterial strains. Deadline: October 13, 2023 Please RT More details: www.uni-osnabrueck.de/universitaet...

Out at Nat Comms: nature.com/articles/s41.... We present a Bayesian framework to evaluate the compatibility of different vaccine descriptions with clinical trial outcomes unlocking impact forecasting from vaccines whose specific mechanisms of action are unknown.
