Atle Harby graduated from the department of hydraulic and environmental engineering at the Norwegian University of Science and Technology in 1988, and has been working as a researcher for SINTEF since 1991. He has more than 20 years of experience in environmental engineering with emphasis on environmental impacts of river regulations, water resources problems, climate change impacts and energy storage technologies. His main interest is in environmental conditions in regulated rivers, aquatic ecosystem modelling, stream habitat modelling and hydrological analyses. He has a strong knowledge and strong interest in greenhouse gas status of freshwater reservoirs as well as topics related to large-scale energy storage including hydropower. He has also strong experience in studies related to hydropower development and environmental impacts in many countries. Since 2009, he is the Director of the research centre CEDREN (Centre for Environmental Design of Renewable Energy), an interdisciplinary research centre for the technical and environmental development of hydropower, wind power, transmission lines and the implementation of environmental and energy policy. Atle Harby was a member of the organizing committee of the first Ecohydraulics Symposium in Trondheim 1994, and the Chairman of the 10th Ecohydraulics Symposium in Trondheim 2014.
