Guillem Francès
I have left the Artificial Intelligence research group.

I studied Computer Science at Universitat Politècnica de Catalunya (UPC), Barcelona, Spain, and completed my PhD at Universitat Pompeu Fabra (UPF), Barcelona in 2017, under the supervision of Héctor Geffner. My thesis research focused on the development of efficient methods for exploiting expressive modeling constructs in domain-independent, classical planning languages. I am a postdoctoral researcher at University of Basel since November 2017.
