Claudine von Hallern

Dr. Claudine von Hallern is a Postdoctoral Researcher at the University of Hamburg, affiliated with the Department of Mathematics within the Faculty of Mathematics, Informatics, and Natural Sciences. Her research focuses on stochastic partial differential equations (SPDEs), numerical analysis, and optimization. She specializes in developing and analyzing numerical schemes for SPDEs, particularly addressing challenges like non-commutative noise conditions and improving approximation accuracy.

Her work includes contributions to the Milstein scheme for SPDEs, CMA-ES algorithms for model calibration, and error assessment in biogeochemical models. She has published extensively in journals such as the Journal of Advances in Modeling Earth Systems and Stochastics and Partial Differential Equations: Analysis and Computations.

Dr. von Hallern’s research trends emphasize advancing numerical methods for stochastic systems, with applications in environmental modeling and computational mathematics. Her recent work (2023–2024) explores exponential stochastic Runge-Kutta methods for Nemytskii-type SPDEs, extending the applicability of derivative-free approximation techniques.

Her academic contributions are supported by collaborations within and beyond the university, though no specific grants or awards are explicitly mentioned. She is based in Hamburg, contributing to the vibrant research environment of the Department of Mathematics.
