Stefano Foletti is a full professor in the Department of Mechanical Engineering at Politecnico di Milano, where he obtained his Ph.D. in 2005. His research focuses on the structural integrity of mechanical components, with a particular emphasis on fatigue strength under multiaxial stress, combining experimental approaches with analytical and numerical methods. In recent years, he has extended his work to the structural evaluation of components produced through Additive Manufacturing (AM), focusing on metamaterials and lattice structures. Since 2017, he has been involved in the MetaMAT Lab, an interdepartmental laboratory at Politecnico di Milano, and has served as its Director since 2022. The lab is dedicated to advanced research in metamaterials, supported by collaborations with leading organizations and industrial partners.
