Haris Doukas (born 1980 in Athens, Greece) is a Greek mechanical engineer and Associate Professor of energy policy and management at the School of Electrical & Computer Engineering of the National Technical University of Athens, Greece. Haris Doukas field of expertise is related with the development of decision support systems for energy and climate policy, placing the human factor at the core of the modelling processes and policymaking towards sustainable development. His integrative frameworks are based on co-creation with citizens, along with co-ownership where feasible. H. Doukas uses linguistic variables for capturing the essence of human behaviour in energy and climate policymaking, enabling the design of policies that listen to “what people want” and “what people can do”, which is fundamental for their success. He has more than 150 scientific publications in international scientific journals with reviewers is the abovementioned fields, he is the co-author of the Greek Book “Multiple Criteria Decision Models for Energy and Environmental Systems”, the co-Editor of the open access Book “Understanding Risks and Uncertainties in Energy and Climate Policy: Multidisciplinary Methods and Tools for a Low Carbon Society” and the co-author of the English Book “Multicriteria Portfolio Construction with Python”. Moreover, H. Doukas is an Associate Editor of the Operational Research International Journal and the General Secretary of the Hellenic Operational Research Society (HELORS). Haris Doukas participates as an expert at the World Renewable Energy Congress / Network (WREC / WREN) where he has received a special award for his contribution, the World Energy Council (WEC) and the EU GCC Clean Energy Technology Network.
