Juan Martín Maldacena (born September 10, 1968) is a theoretical physicist born in Buenos Aires, Argentina. Among his many discoveries, the most famous one is the most reliable realization of the holographic principle - namely the AdS/CFT correspondence, the conjecture about the equivalence of string theory on Anti de Sitter (AdS) space, and a conformal field theory defined on the boundary of the AdS space.
