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 Alon Rosen and Salil Vadhan.
My research interests lie in the design and analysis of algorithms, in computational complexity theory, and their interplay with related areas of mathematics.
In particular, recently I have been thinking about questions related to
- spectral graph theory and its application to clustering and graph partitioning algorithms.
- algorithm design via efficiently computable certificates (in the form of spectral or sum-of-squares proofs).
