I am an independent investigative journalist, mentor, lecturer and trainer. My articles, on the impact of powerful corporations on our environment and climate, appear in the leading Dutch magazine De Groene Amsterdammer
. And my training courses in investigation methods, data journalism and interview techniques have been followed by thousands of professionals and students on four continents.
I co-developed the internationally renowned Story-Based Inquiry
method and co-authored eight books on investigative journalism, including the VVOJ’
s Handbook for Investigative Journalists
(2022) and several handbooks published by Unesco and the Centre for Investigative Journalism (CIJ) in London. I also advise media, investigative teams and NGOs on organizing and implementing investigative projects.
