Prof. Santasalo-Aarnio completed her doctorate in physical chemistry with the catalyst and support material development for fuel cells at the Aalto University School of Chemistry 2012. After this she continued her work with a post doc project on solar energy storage for H2 with bench-scale SO2 depolarized electrolyser. She obtained a university lecturer position for material science and engineering 2015 where she has been involved in recycling of energy devices such as lithium-ion batteries and fuel cells. With the strong collaboration with Helmholtz institute, she has developed new insight in how to take into account recyclability in the planning phase of energy storage solutions. She was appointed as assistant professor of energy conversion and storage at the school of engineering in September 2018 where she will continue the work on renewable energy interaction to energy policy.
