Short CV
Johannes Korte studied Geodesy in Bonn. In 2017 he finished his Master’s thesis. Since then he is working as a scientific assistant in the Theoretical Geodesy Group. In 2019 he started working on time-variable AR process estimation in the project NonStopLSC (DFG project: Nonstationary stochastic processes in least squares Collocation).
