The Summer School on Informatics RIO is an academic event that is organized by the Department of Computer Science of the University of Rio Cuarto, in Rio Cuarto, Cordoba, Argentina. It has been annually organized without interruption (with the sole exception of 2021 and 2022, years in which, due to the COVID19 pandemic, the school had to be suspended) since 1994, and takes place in late February, during Argentina’s summer. It offers intensive one-week courses on topics that span through all areas of Computer Science. The target audience of the summer school is composed of advanced undergraduate students, graduate students and researchers from Argentina and the countries in the region, and the goal is to provide a learning opportunity to keep up-to-date with the latest advances in Computer Science. Thus, the summer school invites distinguished researchers to teach courses on their respective areas of expertise. The school allows us to foster interaction between institutions, to connect researchers and research groups, and to provide opportunities to students to directly interact with top international researchers, and complement their formal education with the latest advances in Informatics. Nearly 4000 students have attended the school, throughout the years. Given the geographical distance of Argentina and South America from the main Computing research centers in the world, concentrated in Europe, North America and Asia, events such as our summer school constitute some of the few opportunities that many students and young researchers have, for in-person interaction with top researchers, and to be exposed to advanced research topics.
