Biography

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.


Teaching activities

Fundamentals of Sensation and Perception: PSYC 363

This course introduces the physiological and psychological mechanisms of Perception. Thorough treatment is given to questions of how information about the world is acquired through visual and auditory systems, and other modalities, that together is used with stored information to create an on-going mental representation of the world. Topics such as pitch perception, color vision, perception of movement, size and space perception, illusions, and perception of distance are covered.

Programming in Psychology: PSYC 725

This course covers basic and more advanced skills in programming in the context of experimental psychology and neuroscience. It focuses mainly on Python and R, as these two environments are open source and increasingly used by researchers and data science professionals. We 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 are covered in R. Emphasis is placed on hands-on learning, developing the tools that students would eventually 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.


Statistical analysis 2: PSYC 316

This course is designed to advance students' understanding of hypothesis testing and statistical inferences. From general linear models to mixed effects models, we highlight the limits of null-hypothesis significance testing and explore alternatives(Bayesian approaches, confidence intervals, effect size, meta-analyses).Students learn how to use programs such as JASP (https://jasp-stats.org/) and R (https://www.r-project.org/).


Research activities

Overview

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, taking a multi-disciplinary approach. Current projects include:1) the neuroplasticity of the brain stimulated by cochlear implants; 2) the cognitive load experienced when listening, understanding, and memorizing; 3) vocal production and control; 4) the challenges of cocktail-party environments; 5) decoding emotion in sounds; 6) bilingualism and prosody.
