We are happy to announce that there will be a pre-Strings workshop in Leuven from July 2 to July 5 2019. This workshop is organized in conjunction with the Strings 2019 conference in Brussels (July 9-13). The goal of the workshop is to provide an overview of important recent developments in string theory, quantum field theory, holography, supergravity and their applications. There will be five comprehensive review lectures which will set the stage for research talks that summarize the state of the art.
