**Dr Yigit Kemal Demirel** is currently a Senior Lecturer (Associate Professor) in the Department of Naval Architecture, Ocean and Marine Engineering (NAOME) at the University of Strathclyde, Glasgow. He is also a member of the University Senate. His research interests lie in computational (CFD) and experimental hydrodynamics. He is actively engaged in fundamental and industry-focussed research on the effect of roughness (hull fouling and fouling-control coatings) on ship performance, energy efficiency of ships, hull-propeller optimisation and energy saving devices (ESDs). Dr Demirel worked on a number of internationally collaborated projects, published numerous papers in highly ranked journals and presented his research at several international conferences and workshops. In 2017, Dr Demirel was appointed to the Resistance and Propulsion Committee of the International Towing Tank Conference (ITTC), which sets best-practice standards for large-scale hydrodynamics facilities worldwide. He was appointed as an Advisory Board Member of the European University of the Seas (SEA-EU) Alliance in December 2019 for a duration of 3 years.
