Previously, he was an Associate Professor at the Center for Computer Games Research, IT University of Copenhagen and among the founders of the procedural content generation research field. Togelius has introduced core procedural generation paradigms and frameworks for game content such as the Experience-driven Procedural Content Generation (EDPCG) framework and the Search-based Procedural Content Generation (SBPCG) paradigm which define two of the leading research trends within procedural content generation. Togelius has worked on several areas in evolutionary computation, in particular a project to unify evolutionary methods in a geometric framework. He has published research on topics such as evolutionary robotics and modularity in neural networks, and continues to work in these areas.
