Jean-Charles Grégoire is a professor in telecommunications sciences at the Institut national de la recherche scientifique (Université du Québec) in Montreal. Choral singing once brought him to CAMMAC on the occasion of a weekend’s retreat. The experience prompted him to experience the summer camps which he has attended regularly for the past decade. Well used to keeping time in irregular meters, he decided to offer his services to keep track of the numbers as treasurer.
