Senni Alho is an Innovations Officer at Clim-Eat, a think-and-do tank bridging food and climate to advance a just transition in low- and middle-income countries. Through foodsystems.tech under the Bold Bets for the Future of Food initiative, she explores and communicates breakthrough innovations in plant nutrition, low-emission livestock, and next-generation crops. With a background in Economics and Business Administration from Aalto University, and experience across consultancy and civil society, Senni brings a multi-perspective approach to linking evidence, innovation, and stakeholder engagement for transformative change in food systems.
Sigrid Wertheim-Heck is associate professor in global food system sustainability at the Environmental Policy Group of Wageningen University, and professor Food and Healthy Living at the Aeres University of Applied Sciences both in The Netherlands. With a master in history, a master in Russian and Eurasian Studies, both from Leiden University, and a PhD in sociology from Wageningen University, Sigrid is interested in processes of societal transformation. As a consumption sociologist, Sigrid takes an ‘everyday fare’ perspective on advancing global food system sustainability. Her research departs from situated perspectives on socio-technical transformations in which evolving practices and arrangements locally are tightly interlinked with the national and global scale. Her interest in urban food systems informs her agenda on the relationship between urbanization, food provisioning and food consumption. Projects across Asia, Africa and Europe bring together three areas of research, namely sustainable food consumption, governance practices and global-local dynamics.
Jillian Student (moderator) is a knowledge integrator and researcher on inter- and transdisciplinary research and learning at Wageningen Institute for Environment and Climate Research and the Environmental Policy Group, Wageningen University and Research. Her research integrates different scientific disciplines, forms of knowledge, and approaches to explore human-environment interactions in the context of environmental change (e.g. environmental degradation, climate change, biodiversity loss). Gaming and simulations are some of the ways she co-creates understanding of complex systems, develops experiences of potential future trajectories, and unpacks future-looking decision-making (e.g. dependencies, differing capacities, uncertainties).
