Isabelle Cossette is a music researcher and director of the Music Performance and Body Lab at McGill University. Her research focuses on respiratory mechanics during music performance, performance enhancement, biomechanics, and instrumental pedagogy. She has published extensively in scientific journals on topics related to breathing patterns during flute playing and uses optoelectronic plethysmography to study performer-instrument interaction and musicians' respiratory mechanics. Cossette also coordinates numerous research lectures and workshops to train students and establish appropriate methods for studying areas of performance.
