About the Author
Deborah Greaves is Professor of Ocean Engineering and Director of the COAST (Coastal, Ocean and Sediment Transport) Laboratory at University of Plymouth and is Board Member and Inaugural Chair for PRIMaRE (the Partnership for Research In Marine Renewable Energy, www.primare.org). Her research interests include marine renewable energy, physical and numerical modelling of violent free surface flow and fluid-structure interaction. She leads and has led a number of research projects concerning marine renewable energy in collaboration with industrial and academic partners. She has published over 125 peer-reviewed papers, has secured £3.9 million research income as PI, is a Chartered Engineer and Fellow of the Institution of Civil Engineers, a Member of RINA (Royal Institution of Naval Architects), and a member of the technical committee for EWTEC (European Wave and Tidal Energy Conference), a reviewer for UK Research Councils, for several journals, and was shortlisted for the 2014 WISE Research Award.

Gregorio Iglesias (GI) is Professor of Coastal Engineering at University of Plymouth and Leader of the COAST (Coastal, Ocean and Sediment Transport) Research Group. He has over 20 years' experience in numerical and physical modelling applied to Marine Renewable Energy and Coastal Engineering, including the characterisation of wave and tidal resources, and the modelling of coastal morphodynamics accounting for the effects of wave and tidal farms. He participates in the design and laboratory tests of WECs and coastal and port structures, and acts as PI on research grants and contracts funded by the European Commission, various national research councils, coastal management agencies and port authorities. He is a member of the IEC Technical Committee for sub-prototype size wave energy device development (laboratory testing) and one of the inventors of the WaveCat, a floating overtopping WEC. Professor Iglesias has published over 100 peer-reviewed papers and secured over £5M research income.
