Angel Uranga
Angel Uranga is a theoretical physicist known for contributions to string theory, particularly in D-brane constructions, string dualities, and applications of geometry to particle physics model building. His work connects concepts from Maria Goeppert Mayer-style configuration approaches to modern frameworks involving Edward Witten-inspired dualities and Juan Maldacena-type holography. Uranga has published extensively on intersecting brane models, flux compactifications, and geometric engineering, collaborating with researchers at institutions including CERN, University of Cambridge, and Institute for Advanced Study.
Uranga was educated in environments influenced by European and Spanish scientific traditions, attending programs and research schools associated with institutions such as Universidad Autónoma de Madrid, École Normale Supérieure, and summer schools linked to CERN and ICTP. During his doctoral training he worked on problems related to supersymmetric gauge theories and string compactifications, engaging with mentors connected to the research networks of Juan Martín Maldacena, Cumrun Vafa, Nathan Seiberg, and Pierre Deligne. His formative education exposed him to the interplay between algebraic geometry exemplified by the work of Alexander Grothendieck and the developments in supersymmetry associated with Sergio Ferrara and Peter West.
Uranga's academic appointments have included postdoctoral and faculty roles at centers prominent in theoretical physics, with collaborative visits to Princeton University, Harvard University, California Institute of Technology, and research stays at KEK and Max Planck Institute for Physics. He has been affiliated with groups working at intersections of string phenomenology and mathematical physics, coordinating efforts with teams at Instituto de Física Teórica (IFT), Universidad Complutense de Madrid, and pan-European projects funded through networks involving European Research Council grants and Marie Skłodowska-Curie actions. His career features organizing international workshops with participants from Perimeter Institute, Simons Foundation programs, and conferences linked to the American Physical Society divisions.
Uranga contributed to the development of intersecting D-brane model building, a program drawing on Joseph Polchinski's D-brane formalism and the realization of chiral gauge sectors via brane intersections. He explored configurations where stacks of D6-branes, D5-branes, and D3-branes produce Standard Model-like spectra by engineering intersections on compactifications related to Calabi–Yau manifolds and orbifolds such as Z_N orbifolds. These constructions interface with Gepner model techniques and the use of orientifold projections introduced in studies by Luis Ibáñez and Angel M. Uranga (note: different person name usage restrictions).
His work on string dualities investigated mappings between Type IIA string theory, Type IIB string theory, M-theory, and heterotic strings, elucidating how T-duality and S-duality transform brane setups and gauge dynamics. He examined geometric transitions related to conifold singularities and the role of fluxes—NS-NS flux and R-R flux—in stabilizing moduli, connecting to the landscape discussions initiated by Michael R. Douglas and Susskind.
Uranga also advanced the technique of geometric engineering of gauge theories by embedding N=1 supersymmetry and N=2 supersymmetry models within string backgrounds, relating brane tilings, quiver gauge theories, and Seiberg duality phenomena. He applied methods from algebraic geometry—such as sheaf descriptions and derived categories influenced by Maxim Kontsevich—to classify D-brane charges and compute chiral indices. Collaborations explored aspects of anomaly cancellation, couplings in effective field theories, and applications to model-building constraints from Large Hadron Collider phenomenology scenarios.

Uranga has been recognized through invitations to speak at leading conferences such as Strings Conference series, plenary lectures at Susy meetings, and visiting positions supported by fellowships from programs associated with European Science Foundation and national research agencies like Spanish Ministry of Science and Innovation. He has co-organized thematic programs with hosts including Perimeter Institute and Simons Center for Geometry and Physics.
As a mentor, Uranga supervised doctoral and postdoctoral researchers who have pursued careers across academia and research institutes such as CERN, Max Planck Institute for Gravitational Physics (Albert Einstein Institute), École Polytechnique, and national laboratories. His teaching has included graduate courses on string theory, supersymmetry, and mathematical methods for theoretical physics at universities modeled on curricula at Universidad Autónoma de Madrid and international summer schools like Les Houches Summer School and ICTP Trieste.
