Jennifer Wittaker - Wild Child Coordinator, PEI

Jennifer Wittaker

Jennifer Whittaker grew up in Charlottetown and her interest in environmental education began when she started working with Agriculture and Agri-food Canada during her second year studying biology at UPEI. There she discovered the joy of working outside and the intricacies of agriculture in PEI. This led her to continue at Dalhousie University where she is finishing up her MSc on determining beneficial management practices in potato production.

She will be coordinating the Wild Child Program in PEI with the Atlantic Canada Chapter of the Sierra Club for summer 2016. Previously, she helped to coordinate a gardening and food literacy program called Start with a Seedling and volunteered with Let’s Talk Science, an organization that promotes curiosity and inquiry in youth. She hopes to continue incorporating the good work that others have done in the forms of science, food and environmental literacy to instill a sense of wonder in youth about their environment.
