Luis J. Garay Elizondo gained his Physics degree from the Complutense University of Madrid in 1988, and the PhD from the Autonomous University of Madrid in 1992. His works and scientific interests have focused mainly on the border between the Theory of General Relativity and quantum phenomena, from quantum theories of space-time to the study of the effects of gravity on quantum systems. Recently, he has gained a Full Professorship at the Theoretical Physics department of the Complutense University of Madrid.
Very frequently, the interest on establishing connections between quantum theories of gravitation (i.e. high energies) and low energy Physics, closer to our experience, has been present in his career. In this field, attention should be drawn to his works on effective descriptions of low energy fields propagating in space-times subjected to quantum fluctuations or, from a completely different perspective, the study of quantum phenomena in intense gravitational fields, like the ones occurring near black holes, by analogies in condensed matter systems.
The attempt to understand the physical phenomena involved in the (quantum) dynamics of black holes has been a matter of his concern in the last years. Black holes admit a simple geometrical description that, on the other hand, cause several complications like the so-called trans-planckian problem or the epistemological problem of being able to distinguish, from an observational point of view, between the High Energy theories than can describe them.
