He received his PhD in Computer Science in the DIVA research lab at the University of Fribourg in 2010. His PhD research was centered around fusion of multimodal input, along three different axes: architectures, modelling and algorithms. The study of these axes lead to the development of a framework for creation of multimodal interfaces (HephaisTK), a XML-based language for the modelling of multimodal human-machine interaction (SMUIML), as well as the development of adaptivity-capable multimodal fusion algorithms.
