Check out our recent paper just out in Physical Review E! journals.aps.org/pre/abstract... with Alice Doimo, @giorgionicoletti.bsky.social, Davide Bernardi We look into stochasticity arising from finite carrying capacity in classical metapopulation models to understand survival statistics.

Finite-size scaling of survival statistics in metapopulation models

Spatial metapopulation models are fundamental to theoretical ecology, enabling us to study how landscape structure influences global species dynamics. Traditional models, including recent generalizati...

Better late than never: it's time to tell you about my main project at EPFL 🇨🇭! What happens in competitive metacommunities when you take into account spatial structure and habitat heterogeneity? Once more, a great collaboration with @lambdapp and the people at @liphlab! www.pnas.org/doi/abs/10.1...

Landscape and environmental heterogeneity support coexistence in competitive metacommunities | PNAS

Metapopulation models have been instrumental in quantifying the ecological impact of landscape structure on the survival of a focal species. Howeve...

🚀 New research alert! 🚀 Led by @gbarzon.bsky.social, @giorgionicoletti.bsky.social and Daniel Maria Busiello, our latest work in Physical Review Letters (journals.aps.org/prl/abstract...) reveals how excitation-inhibition balance tunes the timescale of information coding in neuronal populations! 🧠🔬

Excitation-Inhibition Balance Controls Information Encoding in Neural Populations

Understanding how the complex connectivity structure of the brain shapes its information-processing capabilities is a long-standing question. By focusing on a paradigmatic architecture, we study how t...

Optimal brain processing requires balance between excitatory and inhibitory neurons, study suggests

The brain's ability to process information is known to be supported by intricate connections between different neuron populations.

We have many cool results coming up! So it's the perfect time to tell you about some of the projects we've worked on in the last two years, between UniPD 🇮🇹, EPFL 🇨🇭 and now ICTP 🇺🇳 - starting from ecology 🌲 with @lambdapp.bsky.social and the people of @liphlab.bsky.social www.pnas.org/doi/10.1073/...

Our last paper of the year is finally out in @apsphysics.bsky.social Physical Review Research! We show that active environments lead to "information interference" between interacting particles - but what does that mean? 👇 journals.aps.org/prresearch/a...

Information interference driven by environmental activity

Real-world systems are shaped by both their complex internal interactions and the changes in their noisy environments. In this work, we study how a shared active bath affects the statistical dependenc...
