Short Biography

I was trained in Psychology at Univ Lyon II. I then obtained a Master degree in Cognitive Sciences and a Ph.D. in Experimental Psychology in the same university. I have worked at the Applied Psychology Unit of the Medical Research Council (MRC, Cambridge, UK) as a post-doctoral scientist, and at the Institute of Hearing Research of the MRC (Glasgow, UK) as a junior scientist. I was recruited at the Univ Paris Descartes as lecturer (1997) and then full professor (2001), before taking a position of full professor in Experimental Psychology at the Ecole normale superieure (Paris) in 2011. I am a fellow of the Acoustical Society of America and a former (junior) member of IUF (2001). My research program focuses on temporal processing by the normal and impaired auditory system in humans.
 

Research Interest

My research program focuses on the processing of the temporal structure of sounds by the normal and impaired auditory system in humans. I study the auditory perception of two types of temporal modulations of the acoustic signal, the temporal envelope and temporal fine structure, using various approaches (psychophysics, clinical audiology, computer modeling, developmental psychology, neuropsychology, brain imaging, electrophysiology).

 

 

 

Teaching

I have taught experimental psychology, psychophysics and connexionism at the University of Paris Descartes. I now give lectures in hearing sciences and psychoacoustics in the masters of cognitive sciences from the Ecole Normale Supérieure, EHESS, Université Paris Descartes, and I have been co-ordinating the Psychology strand of this masters degree.
