MSc, Tampere University, 2019
BSc, Tampere University of Technology, 2017

Jussi grew up in Hyvinkää, Finland and after military service moved to Tampere for his higher education. He received his BSc from the Tampere University of Technology where he worked on developing transparent electrodes from nanocellulose and silver nanowires. During his Master studies at the Tampere University, Jussi developed dye-loaded liposomes and spent a semester abroad at the Eindhoven University of Technology, Netherlands. After completing his MSc, he started his doctorate in the same research group. He studied triplet sensitized processes, such as photon upconversion and photoswitching, using steady state and time resolved spectroscopy. He joined the Roberts group in 2022 to investigate the properties of new dye molecules and photocatalytic systems in collaboration with Prof. Zachariah Page’s group. Jussi enjoys music, playing all kinds of sports, and watching football.
