Bienvenue sur ma page professionnelle. Vous pouvez voir ce site en version française en cliquant sur ce lien ou sur le drapeau dans la colonne de droite.

I am currently a tenured research scientist within project-team PANAMA, a.k.a. Parsimony & New Algorithms for Audio & Signal Modeling, a common team of :

  • CNRS (UMR 6074 – IRISA), my employer,
  • Inria Rennes, which fosters me,

which qualifies me as a “frontier-advancing inventor for the digital world”.

Research interests in brief

If you ask me about my job, I will tell you I am a research in audio signal processing. If you are in the same business, you will ask for more. My interests mainly belong to what is usually called computational audio scene analysis, through various angles :

  • Sound source separation and localization,
  • Inverse problems in acoustics,
  • Sparse and cosparse representations,
  • Compressed sensing of acoustic fields,
  • Learning and calibration in audio scenes,

and I am specifically interested in interactions between acquisition, representations, analysis and information extraction, when seen as interdependent levels and not as successive steps of a sequentiel signal processing workflow.

My early research was more devoted to music information retrieval. This theme is sleepy at the moment, but I may go back to it in the future. I am also curious about biomedical signals, musical instrument making, hearing aids, speech processing… but they are not very active themes for me at the time.

More details on my projects and collaborations can be found on this page.

Short bio

I was born in France in 1981.

I received the State Engineering degree from Télécom ParisTech, formerly known as École Nationale Supérieure des Télécommunications (ENST), Paris, France, in 2004, where I started to specialize myself in signal processing.

I added another M.Sc. degree to my pedigree in 2005, specialized in acoustics, computer science, and signal processing applied to music (ATIAM). The diploma is delivered from the Université Pierre et Marie Curie, Paris, but it is mostly known as “IRCAM master of science”. As a research intern, I had the opportunity to spend a few months with Alain de Cheveigné at Ecole Normale Supérieure (ENS) with the Audition team.

I received the Ph.D. degree in image and signal processing from Télécom ParisTech again, in 2009. My doctoral work was focused on non-negative matrix factorization and its application to music transcription, under the supervision of Gaël Richard and Roland Badeau. My thesis received the “Signal, Image and Vision Ph.D. Award” from Club EEA and GdR ISIS in 2010.

I joined CNRS as a permanent researcher in 2010, and lived happily ever after.
