Portrait Artist, TED speaker
My experience and deep interests:
I am based in: Zwolle
THNK connection: Forum guest


I wowed THNK particpants as a portrait illustrator who discovered the true face of Leonardo da Vinci. In my work at the World Wildlife Fund I was particularly successful in doubling the nature areas in the Netherlands. I outlined how a combination of appealing to enlightened self-interest can contribute to scaling.
