EIC investigations have covered, among others, the murky financial transactions in the world of European professional football, the Malta workings as a pirate base for tax avoidance inside the EU, and the secret dealings of the International Criminal Court.
Recently, while looking for a way to lower the barrier to investigative collaborations, he founded Liquid Investigations.
During the last two decades Stefan participated in co-founding the Global Investigative Journalism Network and helped kickstart several nonprofit ventures related to in-depth journalism (CRJI and The Black Sea) and technology (Sponge Lab)- thus contributing in building a backbone for investigative-related journalism initiatives that stretch across Europe and beyond.
As a long-time member of ICIJ, he managed the Eastern Europe research into the Offshore Leaks project which was in 2012 the first large cross-border investigative reporting collaboration in history.
Stefan has been involved in training and teaching, as well as in critical reflection on the media in his own country and on the cross-border investigative networks internationally.
