Job Description

Numerical simulation plays an important role within the design and development of new products. However, trying to capture “the real” predictive behavior of a product design in terms of performance and reliability is often challenging. Especially in the context of multi-scale problems, the mathematical models need to resolve many scales and consequently are very compute intensive in terms of computational runtime and memory demands. In general, surrogate modelling approaches have been proven to be a viable option to speed-up computational models. However, classical approaches often fail in multi-scale problems within industrial settings.  

In this PhD thesis we want to investigate, how to efficiently speed-up multi-scale problems using surrogate modelling on a specific Bosch use case. Especially in the setting that we want to combine simulation data with measurements to improve the predictive quality. Naturally, the problem setup poses many challenges, out of which are:

  • Modelling the multi-scales with proper surrogates
  • Combine data and simulation with uncertainty within the training phase of the surrogate models to add a notion of reliability
  • Deal with large parameter spaces
  • Approximate strong non-linear functional behavior


  • Education: excellent university degree in applied mathematics
  • Experience and Knowledge: strong knowledge in numerical simulation of ordinary and partial differential equations; good knowledge of machine learning methods (supervised and unsupervised learning), surrogate modelling or model order reduction; strong programming skills, ideally in Python; solid knowledge in probability theory / statistical methods
  • Enthusiasm: interest in solving industrial applications
  • Languages: fluent in English
