Professor Gerasimos Theotokatos

Naval Architecture, Ocean and Marine Engineering

Personal statement

I am the DNV Professor of Safety of Marine Systems at the Maritime Safety Research Centre (MSRC) of the Department of Naval Architecture, Ocean & Marine Engineering at the University of Strathclyde since June 2020. I am the Director of the MSRC, a world-class centre of excellence with a vision to shape the maritime safety, which was established as a significant Industry-University partnership involving the University of Strathclyde, Royal Caribbean Cruise Lines and DNV Classification Society. I graduated from the Department of Mechanical Engineering of the National Technical University of Athens (NTUA) in 1994 and obtained a PhD degree, also from NTUA, in 2001 in the discipline of Marine Engineering. My research focuses on the development of scientific approaches to holistically capture the safety, energy and sustainability interplay of the complex marine systems including cyber-physical and autonomous systems. My research supports the development and use of advanced model-based methods and digital twin tools to address the design of safe, feasible and green alternatives to meet the demanding marine industry requirements, pursuing life-cycle risk and energy management, efficiency improvement, as well as safety and sustainability enhancement.
