Diego Blas was born in Burgos (Spain) in 1979. He graduated in Physics in 2002 from University of Zaragoza and got his PhD in Theoretical Physics in 2008 (University of Barcelona). After some years of postdoctoral researcher at EPFL (École polytechnique fédérale de Lausanne), New York University and the European Organization for Nuclear Research (CERN), he became a staff member of the Theoretical Physics group of CERN in 2014. His work is focused in gravitational physics and theoretical cosmology. In gravitational physics, he specialises in the search for theories which could merge the two cornerstones of the Physics of the XXth century: quantum mechanics and general relativity. His expertise in cosmology is centred around the process of formation of complex structures in the universe (such as clusters of galaxies) from the primordial almost featureless universe. He is also very much interested in possible tests of fundamental physics that can be inferred from cosmological and gravitational observations. He is coauthor of more than 30 publications in prestigious peer-reviewed journals. He is also very much interested in the dialogue between theoretical physics and other disciplines, and in popularization of science. He is a constant collaborator of the different art programs held at CERN.
