Torsten Grust is a professor of Computer Science at Universität Tübingen, Germany, where he leads the Database Systems research group since 2008. Torsten performs research into the design, compilation, optimization, and evaluation of a variety of database languages. In this work, he often walks the fine line between database query and programming language technology. His group develops techniques that turn relational database systems into scalable processors also for non-relational query and programming languages. Torsten is at his happiest whenever he finds new evidence that database and programming language research can mutually benefit each other.
