The Theoretical High Energy Physics group (HEP Theory) at the U. Oviedo works mainly on the many facets of String Theory, ranging from the microscopic to the macroscopic, from 0 to 26 dimensions, and from a single object in String Theory to many.

Participation in Research Projects

• The group participates, and in fact is one of the originators, of the The String Theory Universe research network financed by the EU's COST framework. The Network is roughly organised into the following four Working Groups:
  WG1 - Gauge/Gravity Duality,
  WG2 - String Phenomenology,
  WG3 - Cosmology and Quantum Gravity,
  WG4 - Dissemination and Knowledge Transfer.
  
  For more information see:
  Events organised by the network,
  Short Term Scientific Missions,
  Outreach activities,
  PostDoc and Ph.D. positions.

• The research of the group also financed by the Spanish Ministry of Economy and Competition through the grant Teoría de Cuerdas, Holografía y Supergravedad (Ref. FPA2015-63667-P)
  
  Before the aforementioned grant, the research of the group was financed by the Spanish Ministry of Economy and Competition through the collaboration-grant Teoría de Cuerdas, Teorias Gauge y la correspondencia AdS/CFT (Ref. FPA2012-35043-C02), in which we collaborated with members of the Instituto de Física Teórica and the Basque Foundation for Science.

• The research is furthermore financed by the regional government's Consejería de Economía y Empleo del Principado de Asturias through the grant Grupo de Física Teórica de Altas Energías (GRUPIN14-108).

• The group was part of the TMR network:
  Constituents, fundamental forces and symmetries of the Universe (Ref. MRTN-CT-2004-005104)
  whose local coordinator was Yolanda Lozano.
