Academic Background

I obtained the Master's Degree in Electro-Mechanical Engineering in 1992 and the Doctoral Degree in Applied Sciences in 1997, both at the Katholieke Universiteit Leuven, Belgium. The research group in which I was active, is called SCD (SISTA). In October 2000 I became Research Associate of the Centre National de la Recherche Scientifique (CNRS). I am affiliated with the research group ETIS at Cergy-Pontoise, France. ETIS is associated with the Ecole Nationale Supérieure de l'Electronique et de ses Applications (ENSEA) and with the Université de Cergy-Pontoise. I am Associate Editor of the SIAM Journal on Matrix Analysis and Applications.

My Research in a Nutshell

The theme of my research is signal processing based on multilinear algebra.

Concepts of linear algebra are generalized to the algebra of higher-order tensors. This includes generalizations of key matrix decompositions, like the singular value decomposition. These concepts are used to develop new signal processing methodologies, like independent component analysis and multi-way factor analysis. Some specific applications (mainly biomedical and telecommunications oriented) are studied in more detail.

There will be a special issue of the SIAM Journal on Matrix Analysis and Applications on Tensor Decompositions and Applications (submission now closed).

Recent and forthcoming conferences and workshops:

Workshop on Tensor Decompositions and Applications (TDA 2005), CIRM, Luminy, Marseille, France, Aug. 29 - Sept. 2, 2005.

6th Int. Conf. on Independent Component Analysis and Blind Source Separation (ICA 2006), Charleston, SC, USA, March 5-8, 2006.

ThRee-way methods in Chemistry and Psychology (TRICAP 2006), Chania, Crete, Greece, June 4-6, 2006.

Workshop on Algorithms for Modern Massive Data Sets (MMDS 2006), Palo Alto, CA, USA, June 21-24, 2006.

7th Int. Conf. on Independent Component Analysis and Blind Source Separation (ICA 2007), London, UK, Sept. 9-12, 2007.

Keywords

Keywords for my research interests are linear and multilinear algebra, statistical signal and array processing, higher-order statistics (HOS), independent component analysis (ICA) and blind source separation (BSS), harmonic analysis, factor analysis, identification, blind identification and equalization.
