Harsha Ratnaweera is a Professor in Water and Wastewater Technology at the Faculty of Sciences and Technology, Norwegian University of Life Sciences (part-time from 2001, full time from 2012). He was employed as the Director of International Projects and Innovation at the Norwegian Institute for Water Research (NIVA) 1991-2012, where he initiated and led NIVA's commercialization of research results. He has a Dr. Ing. degree in Civil Engineering (1992) from the Norwegian University of Science and Technology NTNU, and a MSc (Hons) Chemical Engineering (1987) from the National Technical University of Ukraine KPI, Ukraine. He is a Fellow of the International Water Association.

Ratnaweera’s research areas are on modelling and optimization of coagulation processes in water and wastewater treatment; Real‐time monitoring and control of treatment processes; Holistic optimization of sewerage systems; virtual sensors and validation of measurements; membrane process; image analysis for sensor development; water resources management; and harmonisation of water-related graduate studies in Asia, Africa and Eurasia with Norway.

Ratnaweera is the Norwegian representative in the Council of the European Water Association and a member of the Management Committee (MC) of the International Water Association - IWA Specialist Group “Particle Separation”. He has been a member of the Norwegian National Commission for UNESCO and serves as the Chairman and a Board Member in several water and environment related organisations in Norway. He has worked as an advisor/consultant to the World Bank, UNECE, Norwegian Ministry of Foreign Affairs, NORAD and SIDA. He has worked in many countries in Asia, Africa, Eastern and Western Europe and fluent in English, Norwegian and Russian languages.

Ratnaweera has initiated and leading a network of projects involving 82 universities form 52 countries (www.WaterHarmony.net). Water Harmony (www.waterh.net) and Water and Society (www.wasoproject.org) are examples of projects where universities from Asia, Africa and Eurasia are involved and which are coordinated by Prof. Ratnaweera. He has also lead the organisation of four international conferences in IWA Particle Separation Conference, Oslo and EWA Water Management in Cold Climates, Spitsbergen in June 2016, EWA Sustainable Urban Drainage Systems, Oslo, 2019 and 2nd IWA-EWA Conference on Water Management in Cold Climates, Harbin, China in 2020.
