Welcome to my professional webpage! I am a tenured research scientist within the project-team MULTISPEECH (Nancy, France). This is a joint research team of Inria Nancy (my employer), Université of Lorraine and CNRS within the mixed research resarch unit LORIA (UMR 7503).

Research interests in brief

The quickest way to present my research is that I develop mathematical models and algorithms to process and understand audio signals recorded by microphones. Examples of technological applications of this field are interactive robots with auditory abilities, restoration and remixing of music recordings, automatic speech recognition or hearing aids. My research contributions mostly lie within four fields:

  • Audio signal processing : Sound source localization, separation and enhancement
  • Machine learning : Convex and nonconvex optimization, nonlinear regression, dictionary learning, Bayes’ statistics
  • Robot audition : Speaker localization and egonoise reduction
  • Image signal processing / Computer vision : Hyperspectral imaging, face pose estimation


Since January 2016, I am a tenured research scientist (Chargé de recherche) with Inria. I started in the PANAMA research group (Rennes, France) before moving to my current team MULTISPEECH (Nancy, France) in April 2018. I received the engineering B.Sc. (2008) and M.Sc. (2010) degrees in computer science and mathematics from the school Ensimag (Grenoble, France), as well as the specialized M.Sc. research degree in computer graphics, vision and robotics from the Université Joseph Fourier (Grenoble, France). In November 2013, I received the Ph.D. degree in computer sciences and applied mathematics of the university of Grenoble (France), under the supervision of Radu Horaud (PhD thesis available online in English). I was then employed as a postdoctoral fellow for two years (2014-2015) at the chair of Multimedia Communications and Signal Processing of the Friedrich-Alexander-University (Erlangen, Germany) with Prof. Walter Kellerman.

In 2014, I received the French PhD thesis award in signal image and vision, jointly delivered every year by the GRETSI, the club EEA and the GdR ISIS. I also received a best conference paper award at ICIP 2015 and a best journal paper award in 2016. I co-chaired and co-organized four special sessions on various aspects of learning-based audio scene analysis and phase retrieval at the international conferences ICASSP (2016, 2018) and LVA/ICA (2017, 2018). I was the main coordinator of the Journée Science et Musique 2016 and 2017 (Rennes, France), a wide-audience one-day event on the science and technologies behind music and sounds (600 visitors/year). Since Jaunary 2018, I serve as an elected member of the IEEE technical committee on Audio Acoustics and Signal Processing.
