Dr. Michael Kavvadas is Professor Emeritus of Geotechnical Engineering in the School of Civil Engineering, National Technical University of Athens (NTUA), Greece. He holds a Doctor of Science (ScD) Degree in Geotechnical Engineering from Massachusetts Institute of Technology (MIT), USA. His research interests focus on: the investigation of the properties of naturally cemented soils and partially saturated soils with an emphasis on slope instabilities, numerical analyses in Geotechnical Engineering including non-linear material models, underground structures (tunnels, large openings) and deep excavations and the Geotechnics of surface lignite mines. He is the author of over 200 published papers in scientific journals and conference proceedings, attracting more than 2750 citations (Google Scholar h index = 22) and three books. He has given numerous invited lectures in International Conferences and his research has a strong scientific impact. He has participated in numerous research projects funded by the Greek State and EU. Since 2015, he has been a core member of the CEN/EC7 Project Team PT2 for redrafting the Eurocode 7 (Geotechnics). He has worked as a geotechnical consultant in numerous major Civil Engineering infrastructure projects in Greece and other countries related to transportation systems including tunneling, hydroelectric power plants, earth and rockfill dams, marine projects and surface mining projects.
