Alex Lyon is a Postdoctoral Research Fellow with the Centre for Sustainable Food Systems at UBC Farm. She holds a Ph.D. in Environment and Resources (2015) and a M.S. in Agroecology (2009) from the University of Wisconsin-Madison, and a B.A. in Anthropology from Smith College (2004). Her research uses participatory and interdisciplinary methods to advance seed systems for resilient agriculture. In her current project, Canadian Organic Vegetable Improvement (CANOVI) she leads a network of on-farm research sites across Canada to facilitate participatory plant breeding and variety selection in organic vegetable crops including carrot, pepper, and squash. While serving farming communities on a practical level, this work also explores the current and potential role of public institutions in seed and crop development for diversified agroecosystems.
