Welcome!

I am assistant professor in Artificial Intelligence at Linköping University, Sweden. Together with Hector Geffner and Ulf Nilsson, I lead the "Representation, Learning and Planning" lab in the AIICS division. My main research interests are automated planning and its connections to machine learning.

Short bio

I received my MSc in computer science from the University of Freiburg, Germany, in December 2012. In March 2018, I completed my PhD under the supervision of Prof. Malte Helmert with the Artificial Intelligence group at the University of Basel, Switzerland. Afterwards, I stayed on as a postdoc until I became assistant professor at Linköping University, Sweden, in January 2021.
