Oscar García-Prada is a CSIC Research Professor at Instituto de Ciencias Matemáticas— ICMAT. He obtained a D.Phil. (doctorate) in Mathematics at the University of Oxford in 1991, and had postdoctoral appointments at Institut des Hautes Études Scientific (Paris), University of California at Berkeley, and University of Paris-Sud, before holding positions at University Autónoma of Madrid and École Polytéchnique (Paris). In 2002 he joined the Spanish National Research Council (CSIC).

His research interests lie in the interplay of differential and algebraic geometry with differential equations of theoretical physics, more concretely, in the study of moduli spaces and geometric structures. The moduli spaces considered involve objects such as vortices, solutions to general gauge-theoretic equations, Higgs bundles and representations of surface groups and fundamental groups of higher dimensional Kaehler manifolds. Professor García-Prada is the author of a number of papers in journals like Inventiones Mathematicae, Duke Mathematical Journal, Crelle Journal, Journal of Differential Geometry, Topology and Mathematische Annalen, with collaborators in Spain, USA, UK, France, Germany, Portugal, Italy, Switzerland, Canada and India. He is a member of various international committees and serves as editor in several international journals, including the International Journal of Mathematics and the Illinois Journal of Mathematics. He has supervised around 15 PhD theses as well as more than 10 postdoctoral researchers, and has been the Principal Investigator of more than 40 national and international research grants.

He participates regularly in public outreach activities on mathematics and their interactions with physics and music, collaborating with the newspaper EL PAIS, Spanish Radio Exterior, Spanish television RTVE and the Residencia de Estudiantes in Madrid. In parallel with his mathematical work, he carries out a musical activity, singing as a countertenor specialised in the early music repertoire, offering recitals in several countries in Europe.
