Francesco Calvetti is Full Professor of Geotechnical Engineering at Politecnico di Milano, where he teaches courses on soil and rock mechanics, foundations, and soil-structure interaction. He holds a Ph.D. in Geotechnical Engineering from Politecnico di Torino and an M.Sc. in Civil Engineering from Politecnico di Milano. His research focuses on landslide protection structures, numerical methods in geomechanics, soil-structure interaction, granular material behavior, and the effects of global warming on permafrost and slope stability. He has coordinated international projects, serves on ISSMGE technical committees, and is the author of six books and over 40 Scopus-indexed papers (h-index: 16).Graziano Salvalai is Associate Professor at Politecnico di Milano, where he heads the Master’s Program in Architectural Engineering. He holds a Ph.D. in Building and Architectural Engineering and has held research appointments at Fraunhofer ISE, NREL, the University of Colorado Boulder, and Drexel University. His work focuses on innovative construction techniques for decarbonizing the built environment, and he directs the Building Energy facadE performance Lab (BEE Lab). He has coordinated several Horizon 2020 and national projects and authored three books and over 70 peer-reviewed papers (Scopus h-index: 21).
