🎓 Fantastic conference at @NuffieldCollege, @UniofOxford! I'm very grateful for the opportunity to participate in the International Conference on Social Computing (ICSC 2026). I presented our work, “The Shrinking Globe: Structural Evolution and Globalization of the International Migration Network (1990–2024),” during the special session on “Digital and Computational Demography,” chaired by @RidhiKash07. It was also a great opportunity to learn about the work of Satiyabooshan Murugaboopathy, @Carol_Coimbra2, Wenlan Zhang, @OmentiRiccardo, and @LP_CalderonB. I also presented our second work, “Structural Evolution of the Python Dependency Network,” during the session on “Networks, Communities, and Collective Dynamics,” chaired by @JianiYan404. I really enjoyed learning about the research presented by the other speakers: @MicolMorellini, Chenfei Xie, Uku Sildoja, and @InnarLiiv. Beyond the presentations, one of the best parts of the conference was the many great conversations, new ideas, and potential collaborations that emerged over these days. Many thanks to Charles Rahal @OxfordDemSci and the entire team behind the conference for putting together such a stimulating event, and to @RDextrasolar and @ITBA for supporting our work! Looking forward to continuing many of these conversations!

🐍 Structural Evolution of the Python Dependency Network Happy to share that I will present this work at the International Conference on Social Computing (#ICSC) at the @UniofOxford, September 2–4, together with our work on “The Shrinking Globe.” This is joint work with Juan Ignacio Catania, Mateo Guerrero Schmidt, Sofia Gutierrez, and Martina Rosario Pérez. We study how the Python package ecosystem has evolved over nearly a decade by modeling package dependencies as a complex network and comparing two large-scale snapshots, from 2016 and 2025. Our results reveal a massive expansion of the ecosystem accompanied by significant structural transformations: 🔹 The number of packages increased by more than an order of magnitude. 🔹 Dependencies grew even faster, revealing a clear densification of the network. 🔹 Average degree increased while modularity decreased, pointing toward a more interconnected ecosystem. 🔹 The most central packages changed substantially. While earlier stages were dominated by web-development and compatibility libraries, the current ecosystem shows data science, scientific computing, and testing packages emerging as structural hubs. Overall, our findings suggest that the Python ecosystem is evolving toward a more interconnected architecture, following growth patterns observed in other complex networks, including densification and hub reorganization. More broadly, the study shows how Network Science can help us understand the evolution, organization, and robustness of large technological ecosystems. 🙌 Thanks to my coauthors for their great work, and many thanks to Rodrigo Díaz @RDextrasolar and @ITBA for supporting my participation in this conference!

🌍 The Shrinking Globe Happy to share that I will be participating in the International Conference on Social Computing (ICSC) at the @UniofOxford, September 2–4. I will present our paper: “The Shrinking Globe: Structural Evolution and Globalization of the International Migration Network (1990–2024)” Joint work with Viktoriya Semeshenko @VSemesh from @Netlab_IIEP @IIEP_oficial, Alejandro Blasco, Marco Canero, Evangelina Iodice, and Juan Manuel Rodríguez Miguel. We analyze how the global migration system has evolved over the past 35 years, using data from the UN International Migrant Stock and modeling migration as a directed, weighted network connecting countries through origin–destination flows. Using Network Science, we study the topology of the global migration network, its community structure and centrality, and explore four major drivers of international migration: geographic proximity, cultural and linguistic affinity, economic asymmetry, and forced migration. 🔹 Our results point to a progressively more globalized migration system: regional communities persist, but become less cohesive over time. 🔹 Migration corridors increasingly cross traditional regional boundaries, while geographic proximity becomes relatively less important. 🔹 Linguistic similarity emerges as the most stable and consistent cultural factor throughout the entire 1990–2024 period. 🔹 Forced migration is the strongest structural exception: during political and humanitarian crises, geography regains prominence, driving large-scale displacement toward neighboring countries regardless of other factors. Looking forward to discussing these results in Oxford and connecting with researchers working in Network Science and Computational Social Science! #ICSC2026 #NetworkScience #ComplexNetworks

Gracias @Crst_C por la invitación a participar del Summer Institute in Computational Social Science (#SICSS)!

🚀 Muy contento de presentar en @Simposio_ASAID un trabajo que analiza la evolución del ecosistema de Python desde la perspectiva de la ciencia de redes. Hecho con Juan Ignacio Catania, Mateo Guerrero Schmidt, Sofia Gutierrez y Martina Rosario Pérez. A partir de millones de relaciones de dependencia entre paquetes, estudiamos cómo evolucionó la estructura del ecosistema entre 2016 y 2025: cuáles son los paquetes centrales, cómo cambió la organización de la red y qué nos dicen estas transformaciones sobre la madurez y complejidad del ecosistema de Python. Este trabajo surgió a partir de un proyecto realizado por estudiantes del curso de Ciencia de Redes en @Exactas_UBA. Disfruté ver cómo un trabajo práctico puede crecer hasta convertirse en una investigación que termina en un simposio científico. Esta presentación forma parte de la sesión "Ciencia de redes y sistemas complejos", que estará coordinada por Ariel Salgado de @ITBA como Session Chair. ¡Nos vemos en La Plata del 10 al 12 de agosto de 2026! #ASAID2026 #55JAIIO @JAIIO_oficial @SADIO_oficial
