Employment history

Senior Researcher — Lyon Neuroscience Research Center, Lyon, France Auditory Cognition and Psychoacoustics' team . My work concerns the perception of vocal characteristic and concurrent speech perception, in normal-hearing and cochlear implant listeners. I'm affiliated with the Graduate School of Mechanics, Energetic, Civil Engineering and Acoustics (MEGA).
Visiting Researcher — University Medical Center Groningen, ENT Department, Groningen, Netherlands Deniz Başkent's Speech Perception group .
2012/09 — 2014/10
Senior Researcher — University Medical Center Groningen, ENT Department, Groningen, Netherlands Deniz Başkent's Speech Perception group . I co-supervised, with Pr. Başkent, three PhD students working on phonemic restoration and voice perception in normal-hearing and cochlear-implant listeners.
2010/01 — 2012/08
Research Fellow — MRC Cognition and Brain Sciences Unit, Cambridge, UK Line manager: Robert. P. Carlyon. My work focused on concurrent speech perception in cochlear implants. I developed Zebra-speech, a method to mix two speech signals in a purely sequential way while preserving intelligibility, in order to investigate the sequential aspects of concurrent speech perception. In another study, using pulse trains in direct stimulation in cochlear-implants, I compared rate-pitch perception to regularity perception, and found that the two were uncorrelated. While at the CBSU I got involved in local collaborations with Matthew H. Davis, Lorina Nacci, Joni Holmes, Susan E. Gathercole and Richard E. Turner. I also received an Honorary Contract from Cambridge University Hospitals (Addenbrooke’s Hospital), in order to have full access to the Emmeline Centre for Hearing Implants.
2008/01 — 2009/12
Research Associate — Centre for the Neural Basis of Hearing, University of Cambridge, UK Supervisor: Roy D. Patterson. My work focused on auditory integration of speech features, and in particular glottal pulse rate (GPR) and vocal tract length (VTL). I have quantitatively described the role of GPR and VTL in the perception of speaker identity. This work initiated a reflexion on the principal dimensions of the representation of speech in the auditory system. In relation with this reflexion, I contributed to the redefinition of the notion of timbre in musical voice and musical instruments. While at the CNBH, I initiated collaborations with Katharina von Kriegstein (Max Planck Institute, Leipzig, Germany), Damien Gabriel (Geneva University Hospital, Switzerland) and Fabien Perrin (CNRS, Lyon, France).
2004/10 — 2007/09
PhD – Neurosciences Sensorielles, Comportement, Cognition (UMR 5020), CNRS – Université de Lyon, France Supervisors: Nicolas Grimault and Jean-Christophe Béra. Title: “Role of auditory streaming for concurrent voices segregation.” My thesis work was an effort to adapt the Auditory Scene Analysis theory from psychoacoustics to speech perception. The first step has been the design and validation of an objective method to evaluate pitch based streaming with vowels. Spectral and temporal pitch cues have then been manipulated and investigated using spectral smearing, noise-band vocoders and Straight. Most of the work has been performed in collaboration with Eric W. Healy (Department of Speech and Hearing Science, Ohio State University, USA). The thesis is available at (mostly in French).
