Bio

Dr. Marie Spiker is a registered dietitian and social scientist who conducts research at the intersection of public health nutrition and food systems. Dr. Spiker uses mixed methods research and systems science to study food security and its upstream determinants, food systems governance, food systems infrastructure, food loss and waste, and value chains for nutrition. Her work also explores how decision-makers throughout the food system—including food producers, consumers, health professionals, and communicators—navigate complexity and tradeoffs. Her professional practice experience includes municipal food policy and capacity building within the profession of nutrition and dietetics. She teaches undergraduate and graduate courses that prepare students to join an evolving food systems workforce.
