➡️ These inequalities largely emerge from how cities organize activities across urban heat gradients, rather than from group-specific behavior

Using mobility and temperature data across 23 cities, we show that:

• Low-income populations are consistently exposed to higher temperatures
• Commuting trips amplify these inequalities
• And surprisingly, simple mobility models can already reproduce most of these patterns

Mobility shapes heat exposure inequalities in cities Segregation has long been recognized as a driver of environmental inequalities, with disadvantaged groups often living in neighborhoods where heat-related risks are highest. Yet, it remains unclear ho...

New preprint out!! Heat exposure inequality in cities is not just about where people live, but also about where people go.🌡️

🔥 Hey NetPals! NetSci 2025 is almost here, and we proudly present Peercolation!

We're kicking things off with an ice-breaking event, especially welcoming ECRs!

📅 Sunday, 1st June 2025
🕕 6 PM till late
📍 Stadspark, Maastricht 🇳🇱

🔗 More info: netplace.site/event/netsci25/peercolation_social_event

It was a great experience to share these ideas in a fun and relaxed setting! Huge thanks to everyone who came — friends, my lab, and everyone who stayed to chat afterward! 🙌 #PintOfScience #UrbanInequality #MobilityData #ComplexSystems

I shared some early insights from my current project (coming soon to arXiv), and linked it to our work on mobility-based socioeconomic (SE) preferential behavior:

I started with Schelling’s model of segregation to show how even small individual preferences can lead to collective segregation. 🧩

But we don’t spend all our time at home — we commute 🚶, shop 🛒, meet friends ☕...

So how does our daily routine shape exposure inequalities beyond where we live?

Complexity & Networks CORE A hub for the Complexity and Network Science community to gather and share resources.

We are glad to present 𝐂𝐨𝐦𝐩𝐥𝐞𝐱𝐢𝐭𝐲 𝐚𝐧𝐝 𝐍𝐞𝐭𝐰𝐨𝐫𝐤𝐬 𝐂𝐎𝐦𝐦𝐮𝐧𝐢𝐭𝐲 𝐚𝐧𝐝 𝐑𝐄𝐬𝐨𝐮𝐫𝐜𝐞𝐬 (𝐂𝐎𝐑𝐄) 🎉

𝐂𝐎𝐑𝐄 is a newly-created umbrella organization that aims to gather resources and initiatives directed to the Complexity and Network Science community.

We worked on an agent-based network model simulating COVID-19 spread in Catalonia using demographic, mobility, and health data. 🦠

A big thanks to Martine Bosman for her guidance and to all collaborators on this work!

A project I had the opportunity to contribute to during my Summer Fellowship at the Institute for High Energy Physics of Barcelona (IFAE) has recently been published! 🚀

In this work, we explore how the combined effects of pairwise and higher-order interactions influence species coexistence.

💡 Key takeaway: Higher-order interactions alone are not always enough to maintain stable coexistence — species’ physiological rates and network structure matter.

The follow-up from my Master's thesis at @ifisc.uib-csic.es is now on arXiv!

What sustains biodiversity in nature?🌍 Ecological models often assume that species engage only in pairwise interactions, but real ecosystems may involve groups of three or more individuals–i.e. higher-order interactions.
