Professor Garcia-Bellido studies the properties and interactions of the fundamental building blocks of matter. His research is primarily conducted at large particle accelerator facilities in Illinois and Geneva, Switzerland, where the experiments on which he collaborates study the production of new states of matter using the world's highest energy proton beams. His recent work focuses on searching to uncover new phenomena that must exist in order to complete the theory of the microphysical origins of mass. The beginning of collisions at the Large Hadron Collider in Switzerland will offer Professor Garcia-Bellido a new window into a wide variety of possible observables that can point to understanding how nature has chosen to provide the wide range of masses that are observed among the currently known elementary particles.
