Professor Concha Gonzalez-Garcia is a theoretical particle physicist. She studies the fundamental laws that govern the behaviour of the smallest components of Nature: the elementary particles.  Concha does it by comparing the predictions from different theories with measurements performed at accelerators, where high energy beams of matter are made to collide, as well as in experiments which detect the elementary particles arriving to us from outer space, and which were produced in the burning of the stars or during the reactions occurring in the early Universe. The ultimate goal is two-fold: understand the physical laws of the microcosms as well as how they determine the Universe we live in.
