I am an assistant professor in environmental geography and development studies at the Department of Geography, Planning and International Development Studies, Faculty of Social and Behavioural Sciences, University of Amsterdam (UvA). I am also teaching at the Institute for Interdisciplinary Studies, at the UvA Faculty of Science.

My research and teaching  focus on forging links across disciplinary divides—mostly in the areas of political ecology, inclusive development, post-development, degrowth and systems science.

I have also been involved in establishing the Dutch degrowth plaform Ontgroei and leading an action research and social justice programme with practitioners in Bangladesh.

We are so far from circularity! In 2017, the global economy recovered only 8.6% of all waste. Here's my simplified MFA diagram adapted from
