I studied physics in Ghent (MSc in engineering physics), Marseille (PhD) and the École Normale Supérieure in Paris (post-doc). Already in this period my main interests shifted from classic physics to the foundations of the field – a research area in which the fundamental axioms are questioned and investigated. This brought me naturally to philosophy, which I studied at the University of Montreal (PhD). Some of the advantages of working in philosophy are that it allows to address a broad range of interests, and that it somehow incites to look for the unifying ideas, the fashionable ‘big picture’ (I will leave this little idea here very vague). Philosophy also encourages to ask ethical questions on research, technology, science and society. If I would have to summarize my most eye-opening experience of these last years, then it would be the observation that, at the very fundamental level, science and philosophy are solidly intertwined, and can greatly inspire each other. An idea popular among interdisciplinary practitioners, but not yet popular enough in other communities!
