Dr Gerasimos Theotokatos

Reader Of Safety Of Marine Systems

Naval Architecture, Ocean and Marine Engineering

Personal statement

I joined the Department of Naval Architecture, Ocean and Marine Engineering in January 2013 as a Lecturer. 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 various methods of modelling, optimisation and experimental analysis of marine systems and ship energy systems pursuing life-cycle efficiency improvement, reduction of their environmental footprint and enhancing of their safety, promoting feasible, safe and green design/operating alternatives that can meet the demanding marine industry requirements for fuel cost savings and environmental friendliness.
