Dr Ravindra Jayaratne
Senior Lecturer in Civil Engineering, School of Architecture, Computing and Engineering (ACE)
My principal teaching and research interests fall in the field of Coastal and River Engineering, particularly in wave hydrodynamics, wave-structure interaction, sediment transport modelling and disaster prevention mechanisms against tsunamis, storm surges, high waves and Glacier Lake Outburst Floods (GLOF).
I serve as a reviewer for the Maritime Engineering Journal of Institution of Civil Engineers (UK), Coastal Engineering Journal of World Scientific, Natural Hazards of Springer, Ocean Engineering of Elsevier, Canadian Journal of Civil Engineering of NRC and Journal of Marine Science and Engineering of MDPI. I have been awarded a number of grants and fellowships from the Royal Academy of Engineering (UK), the Great Britain Sasakawa Foundation (GBSF), Waseda University, Japan, International Conference Committees and UEL. I am a Fellow of Higher Education Academy of UK since September 2009. Presently I serve as the External Examiner for BSc (Hons) in Civil Engineering programme at University of Plymouth, UK (2015-2019). I am a Visiting Researcher to the Complex Disaster Research Institute of Waseda University, Japan since 2009.
