🎓 Academic Background

Dec 2021 Ph.D. in Computer Science at Polytechnique and UniPi
Oct 2017 M.Sc. in Data Science and Business Informatics at UniPi

🔬 Research

My academic interests primarily lie in the optimization of machine learning paradigms in mathematical programs. Recently, my focus has shifted towards convex optimization, particularly conditional gradient algorithms. This research explores their applications in diverse contexts, such as quantum nonlocality and optimization over intersecting sets.
