Research Assistant Position (f/m/d) (Ref. 26/22)

Work on the MATH+ project DOC-TWIN, which develops a convex-duality framework for reliable error control in PDE-constrained optimal control problems motivated by digital-twin-based structural health monitoring. Tasks include deriving duality-based a posteriori error identities and discrete a priori identities for convergence-rate analysis and certified nonlinear solver control, and designing, implementing and validating finite element methods with adaptive mesh refinement and post-processing.

The project is led jointly by three principal investigators, and the position starts on 1 January 2027.

A very good university degree in mathematics, computational science, engineering or a closely related field, a strong interest in numerical analysis, optimisation, PDEs or scientific computing, and good English. Experience with finite elements, a posteriori estimation, convex or nonsmooth optimisation, PDE-constrained optimisation, elasticity or structural mechanics, and implementation in Python, MATLAB, Julia or C/C++ is an advantage. Full-time (39 hours per week) for two years at TVöD Bund E 13; applications go through the WIAS portal and stay open until the position is filled.
