Sebastian Kühnert

Dr. Sebastian Kühnert is a Researcher at the Department of Mathematics within the Faculty of Mathematics at Ruhr University Bochum. His work focuses on advanced statistical methodologies in functional time series analysis, operator estimation, and asymptotic statistics. He contributes to theoretical developments in Hilbert space-based processes and their applications to real-world time series data.

Research interests include functional ARCH/GARCH models, lagged covariance operators, and invertible processes. He has published extensively on operatorial statistics and functional data analysis, with notable contributions to the estimation of ARMA processes in Hilbert spaces. His work bridges abstract mathematical theory with practical statistical applications.

Dr. Kühnert serves as a reviewer for academic journals and actively presents his research findings in international talks. He is affiliated with the Group Dette within the Institute of Statistics and collaborates on projects related to stochastic processes and their asymptotic properties.
