Jonas Lieth studied Geography at the University of Cologne with a focus on human-environment interactions and geographic information systems (B.Sc., 2016-2019; M.Sc. 2019-2023). In 2021, he joined GESIS, first as a student assistant (2021-2023), and later as a research assistant (2023) for the Horizon 2020 project GRETA (GReen Energy Transition Actions). Since November 2023, he is a research assistant in the DFG-funded project "Expansion of the social-spatial sciences research data infrastructure SoRa" (SoRa+)
