I'm an ELLIS PhD student at Politecnico di Milano, supervised by Prof. Nicola Gatti. As a part of the ELLIS program, I visited Prof. Jiarui Gan at Oxford University. My research lies at the intersection of algorithmic game theory, online learning, and optimization. Specifically, I am interested in combining machine learning techniques with economic paradigms to design algorithms that enable strategic reasoning in competitive, multi-agent environments.
