Congratulations to Parsons SCE Professor Brian McGrath on his contribution to the digital publication of “Designing Brussels Ecosystem,” a collective research project led by Metrolab (a transdisciplinary inter-university laboratory) and a team of international urban scholars and experts. The book explores the state of urban ecosystem in Brussels and provides a critical reflection on the interplay between urban ecologies and urban policies and the role an transdisciplinary perspective can have in fostering our understanding of urban complexity and socio-ecological transition. It is now available online for free.
