I work as Senior Researcher in the Language Technology lab at the University of Helsinki, Department of Digital Humanities, on leave from the French CNRS.

I do research in Computational Linguistics and Natural Language Processing. My interests include data-driven semantic analysis, paraphrasing, text summarization and simplification, and cross-lingual knowledge transfer. My research addresses both theoretical and application-oriented aspects of Semantics. It ranges from explorations on the nature of automatically acquired meaning representations and their adequacy for automatic processing, to the integration of semantic models in NLP applications and automatic evaluation metrics, aiming to improve their performance and increase their correlation with human quality judgments.

I hold an adjunct appointment in the Computer and Information Science Department at the University of Pennsylvania. I am also an associate researcher in the NLP group of the Athens University of Economics and Business.
