Balthasar Reuter

Senior Computational Scientist
Research Department, Earth System Modelling Section, Numerical Methods Group


Balthasar Reuter joined ECMWF in 2019 and investigates modern software engineering techniques such as source-to-source translation and code generation to bring performance portability and accelerator readiness into numerical weather prediction models. HIs scientific background is in numerical methods and parallel computing.

Professional interests:
  • High performance computing and computing on heterogeneous architectures
  • Numerical methods for partial differential equations, in particular discontinuous Galerkin methods
  • Scientific software development: good practices, effective tooling, modern programming styles
