Mickael is originally from France, coming from an engineering background with a strong interest in auditory perception, be it with music or speech. He went to the UK in 2006 to perform his PhD with John Culling on speech segregation by use of differences in fundamental frequency between competing voices. In 2010, he was a postdoctoral student in the US, working on cochlear implants with Monita Chatterjee (Univ. Maryland, now at Boys Town National Research Hospital) and Charles Limb (Johns Hopkins University, now at UCSF), on different studies related to the use of pitch information by implanted children. In 2015, he moved to Montreal, and was working as a research associate in different centers (SCSD and Otolaryngology at McGill, CRBLM, BRAMS, CIRMMT), in collaboration with several professors (Vincent Gracco, Anthony Zeitouni, Alexandre Lehmann). His interests broadened to other clinical populations (e.g. stuttering, Parkinson) and involve neurophysiological techniques (tDCS, EEG, fMRI, fNIRS, pupillometry) in addition to behavioral methods (psychoacoustics). As of 2019, he is Assistant Professor in the Psychology Department of Concordia University. His laboratory focuses largely on cochlear implant research, from audiological to cognitive aspects, and on both ends of the lifespan, with a particular emphasis on pitch.

Programming in Psychology

This course covers basic skills in programming in the context of experimental psychology and neuroscience. It is intended to be very practical - responding to the typical needs of students involved in different labs of the Psychology department - and will focus mainly on Python and R, as these two environments are open source and increasingly used by researchers and data science professionals. We will review basic programming concepts, and apply them directly to various forms of experimental designs using the PsychoPy building platform, from audio/visual stimuli presentation, subject responses, and interface with neurophysiological measurements. Data manipulation, analysis, and visualization will be covered in R. Emphasis will be placed on hands-on learning, developing the tools that students will need in their academic endeavors. The goal is to shape a new generation of scientists that no longer rely on proprietary softwares, including for statistics.

Research activities


My research is primarily about hearing, speech, and cognitive sciences, using a combination of behavioral and neurophysiological techniques. My general goal is to help individuals with sensory loss, more specifically users of cochlear implants. This can be achieved either by improving the technology itself or by reshaping the brain to make the most use of the signals delivered from these devices. Current projects include:1) the impact of tonal languages for processing pitch information; 2) the cognitive effort spent to cope with difficult listening situations; 3) the control of the vocal apparatus in different speech and communication disorders; 4) the challenges of cocktail-party situations.
