Secretary of M.Sc. Computational Science and Engineering


  • Processing of Master's theses
  • Questions and advice concerning examination regulations
  • Forwarding of requests to the examination board (incl. recognitions, prolongations, etc.)
    • Note that these usually need to be approved/checked by the coordinators first!

Please email coordinators@cse.tum.de for queries regarding M.Sc. Computational Science and Engineering, rather than messaging me directly!

Open and running student projects

Topics change (frequently) with my ongoing work and depend mostly on the interests and experience of the student. It is best to contact me directly if you are interested in a thesis or student project.

See also the list of Student Projects at our chair.

Do you want to know what other students are working on in our chair? You are warmly encouraged to attend their presentations at the SCCS Colloquium! Come to get ideas, meet your potential supervisor, or to learn from the style of others for your own presentation.

Open student projects

  • Exploration of influence of boundary conditions in linear solver convergence
  • Hardware-dependence studies in linear solver performance
  • Comparative analysis of existing frameworks on modern architectures
  • Hyperparameter tuning in solver selection pipeline
  • Novel machine learning techniques applied to solver selection
