Dr Hanna Tuomisto is a senior researcher at the University of Helsinki, where she is currently building a research group related to sustainable food systems. Hanna received a master degree in agroecology from the University of Helsinki in 2007 and a PhD degree from the University of Oxford in 2011. She worked as a postdoctoral researcher at the European Commission’s Joint Research Centre in 2011-2015 and at the London School of Hygiene & Tropical Medicine in 2016-2017. Her research interests include the interaction between environmental changes and food systems, and especially how novel food technologies could contribute to the sustainability of food systems in the future. Hanna has contributed to the development of sustainability assessment methods, especially life cycle assessment and carbon footprinting methods. Her work has emphasised the importance of considering the opportunity costs of land use when comparing the impacts of different farming systems. Hanna was the first researcher who estimated the environmental impacts of meat produced by using cell culturing technologies (i.e. cultured meat, in vitro meat or clean meat) and she is currently involved in researching environmental impacts of other novel production technologies too. Hanna’s work on environmental impacts of organic farming and cultured meat has gained wide media attention.
