Michael and Flavia attended the GSP Workshop, held in Madrid from 8 to 10 June 2026.

Flavia gave an oral presentation about the ongoing work “Hodge-Aware Surrogates for Testing Stationarity in Topological Signals,” while Michael gave a talk entitled “Optimal Wiener-Filter Solutions for Denoising Graph Signals on Directed Graphs.”

The workshop brought together three days of talks, poster sessions, and discussions on recent developments in graph signal processing, with many opportunities for exchange and shared dinners in the warm atmosphere of Madrid.
