Institute of Artificial Intelligence

Daniel Höller

I have left the institute in January 2020. This website will not be maintained anymore. You can find my new one here.

I studied Computer Science at Bonn-Rhein-Sieg University from 2007 to 2013 and received my M.Sc. degree in November 2013. From 2009 to 2013 I have been working on Automated Planning at Fraunhofer Institute for Intelligent Analysis and Information Systems in different projects in the fields of Robotics and Multiagent Systems.

I joined the Institute in November 2013. Since then, I am working on Automated Planning and Plan Recognition in the context of the Transregional Collaborative Research Centre SFB/Transregio 62.

You can also find me on DBLP and Google Scholar.

Further Information

I am especially interested in the practical and theoretical aspects of (classical and hierarchical) Planning and related tasks like Plan Explanation, Plan Recognition, Plan Repair and Plan Verification.

The PANDA Planning System

My colleague Gregor Behnke and I are the main developers of the current version of the hierarchical planning system PANDA and its extensions.
