I have 16 years of experience in ocean, coastal and port engineering research and designs including about 1.5 years postdoc research and teaching experiences (UK), 5.5 years in post graduate & doctoral research works (Germany), 3.0 years industry based applied research works (Sri Lanka), 1.5 years on MSc (The Netherlands), and 4.5 years in coastal/marine engineering design consultancy (UAE). I have extensive experiences in numerical and physical modelling related hydraulic/coastal/ocean engineering, including wave-structure interactions, hydraulic performances and stability of breakwaters & geobag structures, wave transformation, coastal hydrodynamics, harbour disturbances, ship motion, dike breaching, etc. During my carrier, I have provided consultancy services for coastal and marine engineering projects in the Europe, Middle East, and Asia-Pacific. I have also been involved with EU research projects on coastal structures. I lived and worked in the Sri Lanka, The Netherlands, Germany, United Arab Emirates and currently resides UK. I’m a holder of a PhD (Dr.-Ing.) Degree in Coastal Engineering from Germany, a Master’s Degree in Coastal Engineering and Port Development from The Netherlands and a Bachelor’s Degree in Civil Engineering from Sri Lanka.
