Since 2011, Thierry Geerts has been heading Google in Belgium and Luxembourg, the company that has become much more than just a search engine. He graduated from the VUB as a Solvay Business Engineer and soon became general manager of an industrial laundry company. 

With the advent of the internet in the mid-1990s, he reoriented himself towards the media industry and held various management positions at VUM (now Mediahuis), publisher of newspapers such as De Standaard and Het Nieuwsblad.
His book Digitalis (2018), in which he describes the possibilities of the digital world, has meanwhile sold more than 25,000 copies. In 2021 he published his new book, Homo Digitalis, about the impact of the digital revolution on people and society.
