I am a researcher and lecturer at Università della Svizzera italiana (USI) and the Chief Operating Officer (COO) of Panua Technologies, a spin off of the university. The focus of my research is centered around HPC algorithms for graph learning and combinatorial and continuous optimization for graph clustering and anomaly detection.
My work is supported by the joint German Research Foundation (DFG) and Swiss National Science Foundation (SNSF) project Numerical Algorithms, Frameworks, and Scalable Technologies for Extreme-Scale Computing.
This is my CV (updated June 2026).
