Luigi Callisto is Professor of Geotechnical Engineering at Sapienza University of Rome, where he teaches soil mechanics and geotechnical earthquake engineering. As a member of a Eurocode 8 Project Team, he contributed to the drafting of the provisions on earth retaining structures for EC8 Part 5. He has been involved in the development of additional technical codes, including the Italian technical code for the design and maintenance of dams and the Italian National Building Code. He has advised on major engineering projects, including the assessment of the effects of excavations and tunnelling on historic monuments and buildings along Rome’s Metro Line C and the evaluation of the seismic performance of existing large earth dams. In 2026, he co-founded Interact – Geotechnical Analysis, a spin-off company of the Sapienza University specialising in advanced geotechnical engineering analysis. His research and professional activities focus on geotechnical earthquake engineering, soil-structure interaction, underground construction, and the seismic behaviour of geotechnical infrastructure.
