I am an earth scientist and urban expert based in Amsterdam. As a sustainability consultant at Metabolic, my work includes mapping urban metabolisms and developing evidence-based interventions for circular cities and high-impact sectors. I've given dozens of talks on circular economics for academia and industry across Europe and Taiwan, and co-founded the world’s first summer school on circular cities.
I am also a PhD candidate in ecological engineering, an emerging field which predicts, designs, restores, and manages ecosystems that integrate human society with the natural environment for mutual benefit. In 2018, I was selected for the New Amsterdam Council, the DJ100 (jury-selected list of the Dutch top 100 most sustainable young changemakers), and one of the top digital talents under 26 by The Next Web. I was born in the Netherlands and raised in Canada.
