Additional information

I have more than 15 yearsof experience in ocean, coastal and port engineering research and designs including6 years in post graduate, doctoral & post doctoral research works, 3.0 years in industrybased applied research works, 1.5 years on MSc, and 4.5 years in coastalengineering design consultancy. I have extensive experience in numerical andphysical modelling, including wave-structure interactions, hydraulicperformances and stability of breakwaters & geobag structures, wavetransformation, coastal hydrodynamics, harbour disturbances, ship motion, dikebreaching, etc. During my carrier, I have provided consultancy services forcoastal and marine engineering projects in the Europe, Middle East, andAsia-Pacific. I have also been involved with EU research projects on coastalstructures. I lived and worked in the Sri Lanka, The Netherlands, Germany, UnitedArab Emirates and currently resides UK. I’m a holder of a PhD (Dr.-Ing.) Degreein Coastal Engineering from Germany, a Master’s Degree in Coastal Engineeringand Port Development from The Netherlands and a Bachelor’s Degree in CivilEngineering from Sri Lanka.
