Zachari B. Jolin has been a science guide at the Montréal Biodôme since 2012. He completed a bachelor’s degree in ecology as well as a master’s in environment at Université de Sherbrooke. Although he specialized in tropical-forest ecosystems and the links between humans and ecosystems, through agroecology, Zachari has always had a special interest in unusual scientific subjects, such as parasites. A seasoned guide, he is currently pursuing a diploma in teaching higher education at Université du Québec à Montréal (UQAM) so that he can teach biology at the CEGEP level.
