Hi! I am a PhD student in the Stat&CS program at Bocconi University. I was advised by Luca Trevisan until mid of 2024. Lately I have been co-advised by Salil Vadhan and Alon Rosen.
In the summer of 2026, I am a visiting graduate student at EPFL, kindly hosted by Ola Svensson.
In the fall of 2026, I will be a visiting graduate student of the research program Spectral Theory Beyond Graphs at the Simons Institute. I will attend remotely because of US visa.
My research interests lie broadly in the design and analysis of algorithms, in computational complexity theory, and their interplay with related areas of mathematics.
My PhD work has been on analyzing and using eigenvalues and eigenvectors in various settings, especially for graph matrices. This is related to
- Spectral graph theory
- Graph partitioning(i.e, clustering) algorithms
