MUD2025 at USI: two days dedicated to methods for analysing complex data

On 1 and 2 October 2025, the East Campus of Università della Svizzera Italiana (USI) was bustling with ideas and discussions during the two-day workshop "Multiresolution Methods for Unstructured Data: Past, Present and Future."

Why it matters: Today's science and technology often deal with unstructured data—such as brain networks, social graphs, simulation results, or high-dimensional point clouds. Speakers showed how multiresolution methods (including wavelets, graph-based tools, and multiscale kernel techniques) can be powerful tools for data compression, fast numerical solvers, denoising, and scalable machine learning.

The workshop featured a strong international lineup of researchers: Rémi Abgrall (University of Zurich), Peter Balazs (Austrian Academy of Science), Martina Bulai (University of Turin), Jürgen Dölz (University of Bonn), Wolfgang Erb (University of Padua), Helmut Harbrecht (University of Basel), Armin Iske (University of Hamburg), Mauro Maggioni (Johns Hopkins University), Daniel Peterseim (University of Augsburg), Gabriele Santin (Ca' Foscari University of Venice), Johannes Tausch (Southern Methodist University), Holger Wendland (University of Bayreuth), and Tizian Wenzel (Ludwig Maximilian University of Munich).

The event brought together senior researchers and young scientists alike—professors, postdocs, and PhD students, including several from USI. This mix created lively sessions and engaging discussions. With participants from across Europe and the U.S., the workshop confirmed its truly international spirit.
