Andrei Popescu-Belis


I am a senior researcher at the Idiap Research Institute, a lecturer at EPFL, and the head of Idiap's Natural Language Processing (NLP) group.

My research interests are in natural language processing, machine translation, information retrieval, language and multimodal resources, and the evaluation of linguistic and interactive systems.

I teach a doctoral course at EPFL on Human Language Technology.

Bio and research

I graduated from the French Ecole Polytechnique in 1995, with majors in maths and computer science, and I hold a Masters in AI from the University of Paris VI. I have a PhD in computer science and natural language processing from LIMSI-CNRS, University of Paris XI (1999). I was a postdoc at the UCSD Department of Cognitive Science, and then a senior research assistant at ISSCO, University of Geneva, before joining the Idiap Research Institute as a senior researcher in 2007. I have taught computer science and NLP courses at the Technology Institute in Orsay, the University of Geneva, and the Swiss Federal Institute of Technology in Lausanne (EPFL).

I am the leader of the MODERN SNSF Sinergia project (2013-2016) on Modeling Discourse Entities and Relations for Coherent Machine Translation, which follows the COMTIS Sinergia project (2010-2013), on Improving the Coherence of Machine Translation Output by Modeling Intersentential Relations. I have been involved in the IM2 NCCR from its start (2002-2013), working on dialogue processing, data management and HCI, as head or deputy head of two individual projects. I am contributing to the SUMMA EU project, and I have previously contributed to the inEvent European project (2011-2014), and to the AMIDA European integrated project (2007-2010) as head of a work package on interfaces and evaluation.
