Gabriele Iommazzo

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.
