I will discuss supersymmetric $AdS_3$ solutions in F-theory, that is Type IIB supergravity with non-trivial varying axio-dilaton, which are holographically dual to 2d superconformal field theories preserving at least (0,2) supersymmetries. The aim of this work is to set up holography in the context of F-theory, which are traditionally two distinct areas of string theory. The talk will be based on the arXiv papers arXiv:1705.04679 and arXiv:1712.07631 .
