Research Activities
My research interests are in the fields of Natural Language Processing and Text Mining:
- Morphology and unsupervised morpheme analysis
- Multilingual information management and access
- Educational applications of Natural Language Processing
- Information retrieval and question answering
Unsupervised Morphology Induction
The focus of my PhD was on unsupervised morphology induction. I took part in three editions of the Morpho Challenge competition for unsupervised morpheme analysis in 2005, 2007 and 2009 and applied my systems to several languages: French, English, German, Finnish, Turkish and Arabic.
Multilingual Information Management and Access
I have developed a method for multilingual term extraction from domain-specific corpora based on morphological structure and contributed to the development of a tool for the multilingual enrichment of a concept-based terminology in the medical field.
Besides, I have a strong interest in foreign language learning, as I studied English with a focus on English linguistics and didactics for French native speakers.
Educational applications of Natural Language Processing
I have worked with Zhemin Zhu at the Technical University of Darmstadt on readability analysis and automatic text simplification using a tree-based translation model.
Information Retrieval and Question Answering
From September 2007 to September 2009 I coordinated the QA-EL
(Question Answering for eLearning) project at the Technical University
of Darmstadt, Germany. My work in the realm of this project
focused on the automatic identification of question paraphrases and
semantic information retrieval for answer finding, based on translation models.
I have worked on related topics in the realm of the QUAERO project, with a focus on morphology and paraphrasing for Question Answering.

Biographical Information
I obtained an MSc in
Computer Science at the Pierre Mendès-France University of Grenoble in 2002 and
an MSc in Cognitive Science at the INPG (Grenoble) in 2003. I defended my PhD on November 30, 2006 at the Joseph Fourier University of Grenoble. From September 2007 to September 2009, I was a post-doctoral
research scientist at the Ubiquitous Knowledge Processing Lab in the Computer Science Department of the "Technische Universität Darmstadt", Germany. From October 2009 to August 2011, I worked as a post-doctoral research scientist at the Computer Sciences Laboratory for Mechanics and Engineering Sciences LIMSI-CNRS, in the ILES group.
Languages
I have a passion for languages which I like to date back from my early childhood, when I was raised with two languages by my parents (French and Alsatian, which is a Germanic dialect talked in the North-East of France). Since then, I have learned to speak fluent English and German and like to work on many different languages.
