Dear Colleagues, We are glad to announce the summer school Mathematical methods for high-dimensional data <https://sites.google.com/view/math-high-dimensional-data/home>, which will take place on September 8-12, 2025, at the Mathematics Department of Sapienza University of Rome. Lecturers of the school are Jean Barbier (International Centre for Theoretical Physics) Marylou Gabrié (École Normale Supérieure) Alessandro Ingrosso (Radboud University) Silvia Villa (University of Genova) The school will also include poster sessions for PhD students and early postdocs. To register, please complete the form available on the website (here the link <https://sites.google.com/view/math-high-dimensional-data/registration?authuser=0>). Participation is free, but registration is mandatory. The school will launch the Eccellenza Scientific Program dedicated to Data Science, running through January 2026. This program features workshops, doctoral courses, and seminar series, focusing on the mathematical methods underpinning data science. Participants will engage with cutting-edge methodologies in statistical physics, statistical inference, optimization, and control, alongside advanced techniques in numerical simulations and scientific computing for machine learning. By integrating these disciplines, the program provides an overview of rigorous foundations and tools for tackling real-world challenges through data-driven approaches. More about the program will be found on this page <https://sites.google.com/view/math-high-dimensional-data/home>. For additional information, do not hesitate to contact us. Best regards, The organisers of the school Elena Agliari Emanuele Caglioti Alberto Fachechi Lorenzo Taggi -- Alberto Fachechi, PhD Researcher (RTD-A) Dipartimento di Matematica G.
