Kevin is an ESR working at Olympia Electronics in Greece while being enrolled as a PhD with the Università degli Studi di Napoli Parthenope in Italy. Before his PhD he first did a Bachelor’s in International Business Administration in the Netherlands and Greece, followed by a master’s in Innovation Management with the Universities of Trento and Sant’Anna. He wrote his master thesis on open innovation initiatives by the Dutch government. Working as a consultant in the Philippines, he developed an interest in saving the environment and started pursuing a career in this field, culminating in taking this ESR position.


As Early Stage Researcher Kevin will devote his time to material streams identification and evaluation. Researching this with the aid of Olympia Electronics he will try to:
-Develop methodologies for material streams identification and evaluation.
-Identify regulatory, organisational and technical solution that are capable to remove barriers and promote increased circularity.
-Identify and evaluate circular patterns.
-Identify and evaluate the potential of establishing Eco Industrial Parks
His research will have a specific focus on the electric and electronic equipment industry in particular.
