He has contributed to very important phenomenological studies of elementary particles of the second and third generation, such as tau, charm, bottom and top, as well as the phenomenology of the Higgs boson, co-signing more than 1700 papers in scientific journals with peer-review, including:
• the discovery of the Higgs boson
• the observation of the oscillations matter-antimatter Bs(0)/antiBs(0)
• the discovery of the electroweak production of the top quark, the single-top,
• the precise measurement of the mass and width of the Z0 boson
• the number of neutrino light families
• the precise properties of the tau lepton
He has coordinated and participated at local, national and international level many outreach activities, as the Masterclasses for High Energy Physics, since 2005, organized by IPPOG; Spanish contact for CERN-Beamline; scientific conferences at the Ateneo in Santander, …
He contributed to the development of the World Wide Web at Spain, were the first web page was constructed by A. Camacho, in the Cantabria node, under A. Ruiz direction.
He was also the principal investigator of a European network called "Technical development for LEP detectors"
