He has also lectured at several universities and educational institutions in Sri Lanka. Currently, he teaches Additive and Subtractive Manufacturing Engineering and Product Development to B.Sc. students, as well as Welding and Inspection Technologies to M.Sc. students. Additionally, he offers two Ph.D. courses focused on the use of AI in asset management, Risk-Based Management, Integrity Management, Supply Chain Management, Lean Management, Welding, and Multi-Criteria Analysis.

Professor Ratnayake also conducts training courses for practicing engineers in both the oil and gas industry and the manufacturing sector, at both national and international levels. He has been invited to speak at numerous international conferences on a wide range of topics, including asset integrity assessment and control, health, safety, and environmental issues, sustainability, maintenance, criticality analysis, risk-based inspection, reliability-centered maintenance, offshore data management, and human factors.

He is currently involved in managing several NORAD NORHED II projects, which focus on implementing circular economy practices in the supply chains of plastic waste, agricultural waste, and healthcare sector waste. Additionally, he is engaged in the EC Horizon project AIdesignTEX, which centers on textile waste management and circular economy solutions. He also contributes to Erasmus+ and Nordplus projects, as well as the application of lean concepts and the effective adoption of enterprise resource planning (ERP) systems within Norwegian industries.

In addition to his teaching and industry contributions, Professor Ratnayake supervises B.Sc., M.Sc., and more than 10 Ph.D. students and has authored more than 200 scientific publications in peer-reviewed journals, conference proceedings, and book chapters. He serves as an associate editor for the ASME OMAE Journal, the Central European Journal of Engineering (Industrial Engineering/Offshore Engineering), and ScienceDomain International.
