      The Institute of Food, Nutrition and Health (IFNH) is composed by about 250 members including doctoral students, postdoctoral researchers, and scientific and technical/administrative staff. It is led by twelve professors (7 full, 2 associate, 3 assistant and 1 titular professors) in laboratories covering key aspects of the entire food value chain, and involved in the teaching of two curricula: Food Science and Nutrition and Health Sciences and Technology. https://ifnh.ethz.ch/

    • Professor of Sustainable Food Processing at ETH Zurich
      Sep 2022 - Present · 3 yrs 11 mos

      https://sfp.ethz.ch The Sustainable Food Processing group focuses on a system oriented approach in food production via the consideration of the total value chain including emerging needs in society and their environmental, economic and social impact. Sustainable Food Processing is part of the global bioeconomy. A multi-​indicator sustainability assessment as guidance tool is the foundation of our emerging food process development. Selected mechanical, biotechnological, thermal and non-​thermal techniques to realize several objectives such as i) biomass and (ii) energy use efficiency, (iii) significant waste reduction along the food value chain and (iv) healthy and high quality food production are evaluated. Innovative raw materials from algae and insects are utilized within urban farming and processing concepts to enable new ways of sustainable food supply.
