Universitat de Barcelona
La Universitat de Barcelona és la universitat pública principal de Catalunya, amb el nombre més gran d’estudiants i l’oferta formativa més àmplia i completa. A més, és el principal centre de recerca universitari de l’Estat i un dels més importants d’Europa, tant per nombre de programes de recerca com per l’excel·lència assolida en aquest terreny.Estretament vinculada a la història de Barcelona i de Catalunya, la UB combina els valors de la tradició amb el fet de ser una institució innovadora i d’excel·lència en l’àmbit docent, i és una universitat urbana, oberta i cosmopolita com la mateixa ciutat de Barcelona.Us convidem a conèixer la Universitat de Barcelona!
