ON LEAVE since 31/12/2018
I obtained my PhD (UAM 1994) working on Particle Physics beyond the Standard Model at IEM (CSIC, Madrid) under the supervision of Mariano Quirós. After postdoctoral stays at DESY (Hamburg, Germany), University of Pennsylvania (Philadelphia, USA) and CERN (Geneva, Switzerland), in 1999 I joined IMAFF (CSIC, Madrid) and then IFT-UAM/CSIC (Madrid) with a permanent position as 'Científico Titular' being promoted to 'Investigador Científico' in 2005 and to 'Profesor de Investigación' in 2008. In November of that year I joined ICREA as Research Professor to work at IFAE.
The ultimate goal of my field of research, Particle Physics, is to understand nature at the most fundamental level determining its building blocks and the laws that govern them. In the path (of ever increasing energies) towards that goal, the Standard Model -the theory that describes how all phenomena observed so far can be explained in terms of a small number of particle species interacting according to a well defined mathematical framework- stands as an impressive achievement. In spite of this, it leaves open too many questions to be considered the ultimate theory, and strong reasons lead us to believe in physics beyond this Standard Model. As a theorist, I work at this high energy frontier exploring what theories might supersede the Standard Model and what experimental implications they would have. The Large Hadron Collider now in operation at CERN and a other experiments will provide us in coming years with crucial data to guide research in this fundamental field.
