We kicked off the workshop with our first invited talk by the incredible Rafael Prieto-Curiel, who shared insights from his work studying how cartels operate in Mexico, sparking lively discussion and great questions. A fantastic start, and more to come!

🎤 We are delighted to announce our first of #WWCS26 speaker: Rafael Prieto-Curiel (CSH Vienna)! With experience at Oxford, UCL & as Director of Strategic Analysis in Mexico City, he applies complexity to violence, migration, mobility & urban dynamics. See you in Mallorca! ❄️🌍

Hace unos meses se publicó nuestro estudio en @science.org sobre los cárteles en México. Nuestros resultados muestran que: - Juntos, los cárteles son el quinto empleador del país - Reclutan 350 jóvenes por semana www.science.org/stoken/autho...

In 2026, I am launching a vlog, For the Love of Science, about working aspects of being a scientist - the joys and challenges, the practical aspects and mental and emotional qualities it involves. It's on YouTube (at @NAChristakis) and Instagram (at @OnTheLoveofScience) www.youtube.com/@NAChristakis

We are excited to welcome @rafaelprietocuriel.bsky.social as a 2026 keynote for IC2S2. His work at the Complexity Science Hub in Vienna, as well as his work with OECD - OCDE and the The World Bank focuses on mobility, migration and urban dynamics:

Constructing better cities could result in approximately 220 million more people having access to water. Here is our article covered by @newsweek.com. www.newsweek.com/cities-water...

Compact urban design is key to securing water and sanitation, a new study by CSH and the World Bank in #NatureCities shows. With horizontal city growth, 220M fewer people could have access to piped water and 190M to sewage by 2050, says lead author @rafaelprietocuriel.bsky.social shorturl.at/WFhvr

Big fan of this paper, which I reviewed for Nature Cities. If you didn't think urban form and water access were related...

In our latest paper, with colleagues from the World Bank, we quantified how urban form shapes water access. Compact city growth could deliver piped water to 220 million more people and sewage services to 190 million more people in Africa, Asia, and Latin America. 💧🏙️ www.nature.com/articles/s44...

Cities are often seen as hotbeds of violence, with the assumption that bigger cities are more dangerous. New research by @rafaelprietocuriel.bsky.social ( @csh.ac.at ) and @ronaldomenezes.bsky.social ( @exeter.ac.uk ), published in #NatComms, highlights that 𝐢𝐬𝐨𝐥𝐚𝐭𝐢𝐨𝐧 𝐦𝐚𝐭𝐭𝐞𝐫𝐬. shorturl.at/ii3jm

Large cities are often assumed to be more violent, but our review shows there’s nothing universal about urban violence. In our new study, @ronaldomenezes.bsky.social and I show that isolated cities tend to experience higher rates of violence against civilians. www.nature.com/articles/s41...

Our new study challenges assumptions about urban violence in Africa. Surprising finding: isolated cities face 4x higher violence risk than large, connected cities. Size matters less than connectivity. Amazing work with @rafaelprietocuriel.bsky.social nature.com/articles/s41467-025-65728-6

I am glad to be back at @ox.ac.uk to present the research of my team at @csh.ac.at on cities at @inetoxford.bsky.social! See you later today! 🌇 www.inet.ox.ac.uk/events/citie...

I analysed the modal share of nearly 400 European cities, comparing those with a metro, only a tram, and without any rail system. Large cities with a metro have roughly half the car share of cities served only by a tram. www.nature.com/articles/s44... Data: CitiesMoving.com

How can car traffic in cities be reduced? New research by CSH's @rafaelprietocuriel.bsky.social shows that while metros are effective in reducing car traffic, a study of nearly 400 European cities finds no evidence that trams have the same effect: csh.ac.at/news/metros-...

🌐 How can we address organized crime? Last week, we hosted a #workshop, organized by @rafaelprietocuriel.bsky.social, exploring the complexity of violence – including cartels and their recruitment practices, social media dynamics, crypto crimes, and law enforcement strategies

This week, we had the honor of welcoming @sergioaguayo.bsky.social and his team from Colmex to @csh.ac.at. Throughout the week, we discussed science, violence, migration, politics and more. This Wednesday, his column in Reforma was dedicated to complexity and violence. ⚗️🥼🔬

Congratulations to Dr. Rafael Prieto-Curiel, winner of the Junior Scientific Award 2025, for his contributions to complex systems research through innovative mathematical modelling of social phenomena🎉

Now at the criminal complexity satellite, @rafaelprietocuriel.bsky.social just gave a wonderful talk showing his progress when modeling organized crime recruitment by Mexican cartels. His results show that current Mexican and US policies are not enough to effectively reduce recruitment. #CCS2025

We are excited to invite you to Criminal Complexity, our Satellite Event at #CCS2025 in Siena, focusing on Crime, Violence, and Complexity Science! Join us for a series of talks that explore the intersection of criminal phenomena and complex systems. criminalcomplexity.weebly.com/programme.html

While in Vienna, CSH resident journalist Will Grimond was fascinated to learn about grätzloase--neighbourhood oasis made by and for residents to enjoy shared urban life. And he wrote a story about it for @theguardian.com (featuring @rafaelprietocuriel.bsky.social and @csh.ac.at): shorturl.at/gC6Ch

🚶🚌🚗 Where you live in a city shapes how you commute. @rafaelprietocuriel.bsky.social (CSH) & Filipe Barroso (Universidade de Aveiro) analyzed Lisbon & Porto and found: car use rises ~1% every 2 km from downtown, reaching 75%+ in outer neighborhoods. Over the decade, car trips increased nationwide.

🚔 #Crime has a rhythm — can we decode its beat? In a new study co-authored by CSH's @rafaelprietocuriel.bsky.social, 12 years of detailed crime data reveal relatively stable temporal “heartbeats” for different crime types over time. journals.sagepub.com/doi/10.1177/...

No, it's not the case that only China is responsible for the large decline in extreme poverty over the past decades. We wrote about it recently: ourworldindata.org/data-insights/was-the-global-decline-of-extreme-poverty-only-due-to-china

Migration is shaping the future of our societies — but how can research help shape migration policy? Last week, the #HumanMigration research group led by @rafaelprietocuriel.bsky.social hosted a three-part event series at the Complexity Science Hub to explore this pressing question.
