Proof of Brauer's Height Zero Conjecture was completed in 2024 by Gabriel Navarro Ortega alongside G. Malle, A. Schaeffer-Fry, and P. H. Tiep. This work, published in Annals of Mathematics, serves as a cornerstone of his career in finite group representation theory, following decades of contributions to the field of applied mathematics.
Academic Background
Born in 1964 in Sueca, Spain, Navarro completed his PhD at the Universitat de València in 1989. His training included a Fulbright post-doctoral position where he worked under the supervision of I. M. Isaacs. He currently serves as a full professor at the Universitat de València.

Take the IQ test →Advances in Representation Theory
Navarro has focused his research on the representation theory of finite groups and group theory. His work on the McKay conjecture remains central to his output. Together with I. M. Isaacs and G. Malle, he reduced this conjecture to a question concerning finite simple groups, providing the essential framework that allowed M. Cabanes and B. Späth to achieve a final solution in 2024. He has also expanded this area of study through the Galois-McKay conjecture, which incorporates Galois automorphisms.
Conjectures and Collaborative Proofs
His investigative record includes significant papers on the Alperin Weight Conjecture, notably a reduction theorem developed with P. H. Tiep in 2011. His 2018 book, Character theory and the McKay conjecture, published by Cambridge University Press, synthesizes much of this complex mathematical terrain for the field.
Professional Recognition
The international mathematical community has acknowledged his research through several formal appointments and honors. He is a Fellow of the American Mathematical Society, an honor he received in 2015, and is a Distinguished Speaker of the European Mathematical Society. In 2025, he was awarded the Medal of the Royal Spanish Mathematical Society.
