  •  Since October 2017 I am a Data Scientist at Siteimprove where I pursue research in Natural Language Processing and develop tools that help our customers maintain and improve their websites.


  •   Before that, I was a postdoctoral researcher (from October 2016 to September 2017) at the Department of Computer Science of the University of Copenhagen in the CoAStaL group and worked on the LOWLANDS research project (ERC).
My research focused on cross-lingual transfer of information between languages, in particular for low-resource languages and domains, through tasks such as PoS-tagging and discourse segmentation.

  •   Even before, I was a postdoctoral researcher (from March 2015 to September 2016) at the LIMSI-CNRS where I joined the TLP (Spoken Language Processing) group and I took part in the project PAPYRUS.
My research focused on dependency parsing and in particular on learning dependency parsers from partially annotated data.
Through this research, I am interested in cross-lingual transfer of syntactic information, active learning, constrained learning/parsing and domain adaptation.

I was also involved in the Automatic translation and machine learning group. Through this topic, I was interested in word pre-ordering for machine translation and in the use of dependency syntax for translating morphologically rich languages.

  •   I am a Ph.D. in computational linguistics of the University of Nantes in France.  I defended my thesis in December 2014. The subject of my thesis focused on non-projective dependency parsing, including the use of statistical methods through the study of grammar-based and transition-based parsers.
