Elementary Particle Physics is an exciting and challenging field. I work on the experimental side, and the excitement comes from investigating and ultimately understanding the interaction of the fundamental building blocks of nature. The research is carried out both on particle accelerators, where I investigate the breaking of symmetry principles like CP violation in Babar and the Higgs phenomenon at the LHC, and in Space, for which I am preparing the GLAST mission to search for the most powerful accelerators in nature.
