Due to the numerous facets and disciplinary vantage points occuring in circular economy and urban metabolism, the Chair is held by Stephan Kampelmann and Aristide Athanassiadis, two researchers with complementary profiles, experiences and interests. On top of the principal investigators, the Chair is supported by three experts that provide communication, co-creation, design, database structuring support.


Principal investigators


Aristide Athanassiadis

Stephan Kampelmann

Aristide Athanassiadis is a researcher at BATir department of the Université Libre de Bruxelles (ULB) and has a joint-PhD in Art of Building and Urbanism from the ULB and of Architecture and Planning from The University of Melbourne. He is interested in analysing and understanding the socio-economic and territorial drivers of metabolic flows entering and exiting cities to develop strategies and policies that mitigate local and global environmental impact. 

In recent years, he has advised numerous local, regional and international administrations and organizations in the areas of urban metabolism and circular economy through various strategic reports and scientific papers. His research and its popularisation have obtained more than a dozen awards. Finally, Aristide co-created the non-profit organization and the open-source Metabolism of Cities urban metabolism platform. This initiative aims to promote urban metabolism by bringing researchers, data and publications together in a central location and by developing free online tools for teaching and research.

Stephan is an economist by training and holds a PhD in Socio-Economic and Statistical Studies. He is a researcher at the Laboratory Urbanism, Infrastructure and Ecology of the Faculty of Architecture La Cambre-Horta, where he is responsible for the axis "economy / ecology".  He has published several scientific papers on the circular economy, and in particular the problems of measurement and data production at the territorial level. 

In addition, Stephan is the founding member of Centre d’écologie urbaine based in Brussels and OSMOS planning practice based in Amsterdam and engaged in a number of local (Opération Diogène), regional (Opération Tournesol, Opération Phosphore) and european projects (TURAS, Connecting Nature).



Communication and expert support team


Adrian Vickery Hill

Paul Hoekman

Adrian has a background in environmental and urban planning with experience in communications, research and strategy. He has worked in projects involving urban scale sustainability, mobility, agriculture, eco-systems planning, renewable energy networks, housing, urban density, industry and material cycles. He was born in Canada, raised in Australia and Latin America and calls Brussels home. Consulting web developer and urban metabolism researcher. Initial creator of the Metabolism of Cities website while doing research into the feasibility of undertaking an urban-scale Material Flow Analysis in a South African context. Paul is the Acting Executive Director of the International Society for Industrial Ecology. Finally, he enjoys combining IT and urban metabolism research. Freelance Graphic Designer & Art Director, currently enrolled in a Master in Typography at La Cambre (ENSAV). Her projects are mainly focused on brand and editorial design. She has also experience working on web and exhibition design as well as a photographer. She has worked on projects involving environmental & urban issues as she is highly interested in sustainability. She grew up in Mexico city and moved to Europe to make her professional studies.
