I am passionate about open collaboration initiatives, exploring the challenges and opportunities around urban sustainability, and learning from and about nature.

In my work, I have been involved in a variety of initiatives and projects. I have (co-) founded a number of companies and non-profits, and my roles have included that of manager, researcher, web developer, teacher, and consultant.

I was one of the co-founders of Metabolism of Cities and am now working on education and practice of radical sustainability.

I grew up in The Netherlands but spent my adult life in Nicaragua, South Africa and Colombia. I enjoy nature photography and am currently trying to learn more about the fauna and flora in Gauteng, South Africa.

NOTE: I was involved in Metabolism of Cities from 2014-2023 but have now stepped down from my roles in this project. All the best to everyone involved and thanks to all with whom I have shared this great journey. All the best everyone!
