Roshan Ranasinghe joined Teesside University as a Senior Lecturer in Civil Engineering in July 2023 after a tenure at Anglia Ruskin University. Before joining Anglia Ruskin University, Roshan provided his services as a Senior Lecturer at the Open University of Sri Lanka, which is the premier institute in the country for open and distance learning.

Roshan obtained his first degree from the University of Moratuwa, Sri Lanka with a first-class honours in Civil Engineering in 2002. He then obtained his Master's degree and the Doctorate specializing in Coastal Engineering from the University of Tokyo, Japan. Soon after the completion of his PhD, Roshan joined the Department of Civil Engineering, The University of Tokyo as an Assistant Professor and then went on to serve as a Lecturer at the School of Planning, Architecture and Civil Engineering, Queen's University Belfast, UK. He returned to Sri Lanka in 2011 and then made a significant contribution to the development of a couple of non-state sector higher educational institutes in partnership with University of the West of England, Heriot-Watt University and Scottish Qualification Authority.

His area of specialization is coastal engineering, and his research interests include physical and numerical modelling of nearshore hydro-morphodynamics, coastal structures, wave energy converters, and image analysis techniques. Roshan has published several papers in high-impact international journals and peer-reviewed international conference proceedings in coastal engineering.

JRTT (Japan Railway Transport and Technology Agency) Project - 2009

Worked as a co-investigator to identify wave concentration mechanisms and damage along Shimoniikawa coast, Japan due to long-period swell waves and to propose appropriate countermeasures. This project was conducted in-partnership with PARI (Port and Airport Research Institute), Japan.

Nexco Highway Project - 2009

Worked as the numerical modeller (Boussinesq modelling) to simulate nearshore hydrodynamics due to energetic offshore waves and to design qprotection structures for the highway bridge piers at Oyashirasu coast, Japan.
