Project leader

Hannah van Zanten
“A transformation of our food system is required to safeguard our planet for future generations”
More about
Dr. Hannah van Zanten is the project leader of the circular food systems project. She is Assistant Professor at the Wageningen University Animal Production Systems group. It is her ambition to unravel how circular food systems can contribute to producing healthy foods for a growing population within the carrying capacity of the Earth. Hannah graduated cum laude from Wageningen University in 2009 with a master’s degree in Animal Sciences. Her PhD project focused on the environmental benefits of using human-inedible-sources as livestock feed. Since graduating, again cum laude, for her PhD, she continued to work in this research-area with the Animal Production Systems group. She recently was awarded the NWO Talent Scheme grant (VENI) in which she aims to assess the role of animals in a circular food system. Her research shows that farm animals reared under a circular paradigm can play a crucial role in feeding humanity, while reducing the environmental impact.

Postdoc

Marijke Schop - post doc
“Eager to explore the potential of animal production around the world”
More about
Marijke is a postdoctoral researcher at the Animal Production Systems group. After graduating with BSc (2012) and MSc (2014) degrees in Animal Sciences from Wageningen University, she continued as a PhD candidate at the Wageningen University & Research Animal Nutrition Group. Marijke received her PhD in January 2020, for which she studied the kinetics of nutrient digestion in pigs using in vitro, in vivo, and in silico methods. Her current postdoctoral research focuses on the potential production strategies (including feeding and breeding) of animals within circular food systems and their environmental impact.

Anita Frehner
”We need collaboration and creativity to redesign our food systems.
More about
Anita is a PhD candidate at the Wageningen University and Research Animal Production System group and at the Research Institute of Organic Agriculture in Switzerland. She graduated from the University of Bern in Switzerland with a BSc in Economics and an MSc in Climate Sciences with a special qualification in Economics. In her MSc programme, Anita focused on the potential of climate service for smallholder farmers in Peru, in collaboration with MeteoSwiss and SENAMHI. Following her interest in research on sustainable practices on the nexus of agriculture, human consumption, and the environment, she started her PhD in 2017 titled ‘Towards sustainable diets: the role of animal-source food in a planet-friendly and healthy diet’. Anita is now working at the Animal Production System group in-between her PhD and postdoctoral work, focusing on modelling global circular food systems and its environmental impacts.

PhD candidate

Felipe Cozim Melges
“Biodiversity is an insurance policy to maintain sustainable food systems”
More about
Felipe has started his PhD in 2020 at the Wageningen University and Research Animal Production Systems group in collaboration with the Netherlands institute of Ecology. His research focusses on securing biodiversity within circular food systems.
Felipe was born in Brazil, where he graduated at the University of Oswaldo Cruz as an Environmental Engineer in 2014. In 2017, he started the Joint International Master in Sustainable Development at the University of Leipzig, Germany. His MSc thesis focussed on the trade-offs between agriculture economy, food security and biodiversity. Felipe’s specialisation semesters was carried out in Environmental Change and Ecosystems in Universiteit Utrecht in the Netherlands. In 2018, Felipe started working as a research assistant at the German Centre for Integrative Biodiversity Research, where he focuses on the impact of land-use change on biodiversity.

Wolfram Simon
“Using the power of global food system modelling to bring evidence-based knowledge about the complexity of circular food system.”
More about
Wolfram has started his PhD in 2020 at the Wageningen University and Research Animal Production System group in collaboration with the Commonwealth Scientific and Industrial Research Organisation, Australia. His research focuses on the potential of a circular food system on the effect of Nr and P biogeochemical cycles on a national and global scale.
He comes originally from Switzerland where, before starting his academic career, he did a two-year apprenticeship as an organic farmer. He graduated from the University of Kassel in Germany with a BSc on ‘sustainable agriculture’, focusing on alternative protein sources and edible insects. He was awarded the Helmut Claas Scholarship and the Haecker prize for his bachelor thesis, and graduated with honours. In his MSc program at Wageningen University, he focussed on assessing sustainable and climate-smart agricultural systems, and on ecological agroecosystem modelling.
Expertise: Crops, optimization modelling, nutrient flows, global food systems
Junior Researcher

Renée Cardinaals
“Excited to understand the diverse ways in which animals can play a role in our global pathway to a healthy food system.”
More about
Renée is a junior researcher at the Farm Systems Ecology group. She graduated from Wageningen University in October 2020, with an MSc in Organic Agriculture. She holds a BSc degree in Animal Sciences and specialized in animal production systems during the MSc phase. Renée fulfilled both her internship and thesis at the Research Institute for Organic Agriculture (FiBL) in Switzerland. She grew an interest for performing research and decided to continue her career at Wageningen University. She is currently working on her PhD proposal and aims to start a PhD program in 2021. Within the CiFoS team, Renée is responsible for expanding the available data to (further) develop the Global Circular Food Systems model. Besides this, she is involved in the Protein Transition to investigate the shift from animal based diets to plant based.

Ben van Selm
“Applying food system models to fully understand the environmental implications of circularity"
More about
Ben is a PhD candidate at the Wageningen University and Research Animal Production System group and Plant Production Systems group in the Netherlands. The aim of his project is to model the environmental consequences of different circular food system scenarios in the Netherlands where nutrient cycles are closed at different spatial scales (i.e. nationally, with Europe, or globally).
Ben received his BSc in Animal Husbandry (2017) from Van Hall Larenstein, University of Applied Sciences and his MSc in Animal Science (2019) from Wageningen University & Research, specialising in global and sustainable production. In his MSc programme, Ben focussed on integrating healthy and environmentally sustainable diets into circular food systems for which he had already developed and used the CiFoS model. Following this interested in modelling circular food systems in the Netherlands, his PhD was a logical next step.
