Welcome!

I'm about 38 years old, maried and the father of Alexandre and Martin.

I'm maître de conférences (professor assistant) at the University of Saint-Etienne and habilité à diriger des recherches.
I do my research in the Machine Learning Research Team of the Laboratoire Hubert Curien.

I discovered Computer Science at the Ensimag, a high school of the University of Grenoble. However, I chose to write a thesis, do research and teach instead of making a lot of money...

Research

I've investigated a few fields during the last decade:
- During my PhD (<2001), Declarative Programming, Functional Logic Languages, Operational Semantics, Data Types, Rewriting Systems, Narrowing, Graph Grammars, Terms, Term Graphs, Rewriting and Narrowing Strategies.
- Since 2001, Grammatical Inference, Learning Paradigms, String Languages, Automata and Grammars. I also tackled several problems in Grammar Induction, Machine Learning, Noisy Data, Ensemble Methods.
- More recently, I've been working on Distances between Discrete Structures (strings, plane graphs) with applications in Images Classification. From a theoretical standpoint, distances are in the core of several learning problem (e.g., grammatical inference from noisy data); On the other hand, they may be optimized thanks to Learning Techniques (e.g., weights of the edit distance).
I'm involved in several projects:
- the EU PASCAL Network of Excellence. Visit de website of the ZULU Competition.
- the SATTIC project of the ANR, that I coordinate (waoh!).
- the LAMPADA project of the ANR.
I've co-supervised the PhD theses of:
- Henri-Maxime Suchier (with Marc Sebban), now working at Artefacto,
- Rémi Eyraud (with Colin de la Higuera), now professor assistant at the University of Marseille,
- Frédéric Tantini (with Colin de la Higuera), now in postdoc at the LORIA Lab in Nancy.
Finally, I'm co-supervising the PhD thesis of Emilie Samuel with Colin de la Higuera.

Teaching

I've been the manager of the Licence d'Informatique of Saint-Etienne since 2008.
I'm in the teaching staff of the CIMET Erasmus Mundus Master and the Web Intelligence Master of Saint-Etienne.
My main topics are:
- Algorithmics (I prefer this book to this one) and Programming Languages
- Theoretical Computer Science (Formal Languages, Graphs)
