Marios joined the University of Surrey in June 2000 as Professor of Structural Systems. He originally trained as a Naval Architect at the University of Newcastle and MIT, and then read for a PhD in Structural Engineering at Imperial College where he was also employed as Lecturer and British Steel Reader in Structures from 1989 until 2000. Before embarking on an academic career, he worked in industry with Flint and Neill on the design of aluminium bridges and with Det norske Veritas on the reliability of offshore structures.
His research focuses on risk-based performance of structures and infrastructure systems and the development of decision support tools for asset management, for which he has been funded by EPSRC, the European Union and industry. He has published over 150 scientific articles and several book chapters and has lectured widely in the UK and overseas, including a fellowship in Japan sponsored by the Japan Society for the Promotion of Science. He has acted as the convenor of an international working group on structural reliability and probabilistic design, operating under the auspices of the Joint Committee for Structural Safety (JCSS) and has served on national and European advisory and codification committees, including the UK Standing Committee on Structural Safety (SCOSS), the Eurocode 3 Drafting Panel on Shell Structures and the working group on the revision of ISO2394: General Principles on the Reliability of Structures.
These relate to how randomness, variability and uncertainties in human and organisational factors influence the response of structural and infrastructure systems subject to natural and man-made hazards, and the development of risk-based performance standards. Over the past twenty years, a wide range of experimental, analytical and design-orientated studies have been undertaken, encompassing steel and fibre reinforced composite plates and shells, concrete and steel building frames, as well as metallic, concrete and FRP bridges. Increasingly, research has been directed towards the integration of advanced structural engineering and structural health monitoring into consequence analysis and loss estimation in support of risk-informed decision-making tools for structural systems and infrastructure networks. In the course of these investigations, he has supervised over 25 PhD theses and numerous MSc dissertations, has collaborated widely with industry and academics, and has co-authored over 150 publications in archival journals and international conference proceedings; examples of recent research projects include:
• Probabilistic modelling of performance profiles and life-cycle assessment
• Fragility, damage and loss estimation for buildings under seismic loading
• Spatial variability of material properties and deterioration processes
• Imperfection sensitivity and damage tolerance of steel shell structures
• Structural Health Monitoring of metallic bridges
• Repair of metallic structures using FRP materials
• Reliability-based fatigue life prediction of bridges and offshore structures
