You search for new elementary particles. Have you already found any?
One remarkable success was of course the discovery of the Higgs Boson, the theoretical prediction of which won François Englert and Peter Higgs the Nobel Prize. Back then I was part of the research groups at CERN who were involved in proving the existing of the particle.
Have you always been interested in physics?
My father was a biophysicist, so I was already exposed to physics at an early stage. I'm fascinated by the fundamental mechanisms which hold the world together. There are two disciplines which investigate the topic: One is astrophysics, concerned with the large-scale structure of for example the galaxies, and particle physics, which is concerned with the smallest building blocks. I decided in favor of particle physics.
