Dr Gerasimos Theotokatos


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 interests include the ship propulsion plant modeling, the performance and emissions prediction of marine Diesel engines, the development and testing of propulsion plant system control schemes, the analysis of engine and its turbocharging system under normal and adverse operating conditions,  the experimental investigation of performance and emission parameters of internal combustion engines, the investigation of waste heat recovery and emission reduction systems, the techno-economic evaluation of ship propulsion plants and the LNG fueled ships.
