### Description

F-theory was developed in the mid-nineties as a tool to study IIB string theory beyond its perturbative regime. Although conceptually less understood than its "spouse", M-theory, F-theory is a more practical tool for model building mainly because it is anchored to algebraic geometry. This well-studied field of mathematics facilitates spectacularly detailed calculations and provides for endless supplies of explicit examples. Since the year 2008, we have seen a revival of F-theory model building.
In this talk, I will review the basic picture of F-theory and its relation to M-theory. Then, I will summarize the recent developments that triggered the renewed interest in this branch, and sketch the current state of affairs.
In the past few years, myriad works have been produced that focus on embedding particular aspects of GUT-like models into F-theory, such as breaking the gauge group in a certain way, getting the right spectrum, or suppressing proton decay. I will place the spotlight on the fundamental issues that have been addressed and for which understanding is still lacking.
