Who am I?
Coming from the world of discrete mathematics and algebraic logic, I like working on original applications of discrete probabilistic models to Knowledge Representation, Natural Language Processing and related areas in Information Science like Text Mining and Information Retrieval. The goal is to find efficient algorithms to handle discrete aspects of texts like syntax, linguistic rules and underlying conceptual structure.
Bilingual: French/Spanish
Foreign language: English.

Teaching history
I am currently a permanent lecturer at the Institute of Technology of Avignon in the department of Data Science (SD). Before coming to Avignon in 2006, I was appointed as an assistant lecturer first in 2000 at the Institute of Technology 2 in Grenoble, then in 2001 at the University Claude Bernard - Lyon 1, and in 2002 I was nominated as lecturer at the Institute of Technology of Metz.

Research activities
Publications HAL,DBLP,Google Scholar
My research interests revolve around Discrete Mathematics, Knowledge Discovery, Natural Language Processing (NLP), Information retrieval and Cultural Heritage.
The phd's I supervised over these topics are listed in theses.fr
Before these projects, I have been working on the theoretical side using algebraic logic formalism:
- Heyting Algebras with operators as a generalization of Rough Set Logic
- Closure operators in collaboration with Anne Berry and Alain Sigayret
Organisation of scientific activities
- CLEF MC2 lab that aimed to evaluate microblog retrieval and contextualization.
- CLEF 2018 conference in Avignon.
