Her love of the environment and of human nature led Isabelle St-Germain to studies in biological sciences. Following a research project with coffee-growing communities, she worked for over 15 years at Équiterre and contributed to the strategic development of that organization as deputy director. At Oxfam-Québec she devoted herself to communications and to public involvement as the organization’s senior director. Her career has allowed her to acquire solid experience in the fields of the environment, social innovation and international development. She has entered into numerous partnerships and served on several boards of directors in relation to the environment and social justice. In July 2021 she became director of the Biosphère.
