An engineer by training, he is specialized in the energy-society interface. His current research bridges across disciplines such as engineering, behavioural economics and psychology to develop policy frameworks that improve the effectiveness and social acceptability of sustainable energy innovations.
Constantine holds a Ph.D. in Civil Engineering- Energy Technology from the Hong Kong University of Science and Technology (HKUST), where his thesis explored how artificial intelligence (AI) models can be used to explain the role of human feelings, values, judgment and preferences in energy decision-making. He also holds a Ph.D. in Chemical Engineering- Fluid Dynamics from Imperial College London and an M.Sc. in Environmental Technology from the same academic institution.
Prior to joining the ESRI, Constantine worked as a postdoctoral researcher and a lecturer at HKUST, and as a data scientist in the energy technology and AI industries.
