## Melina Freitag

## Professor for Data Assimilation

My research is at the interface of numerical analysis, numerical linear algebra, computational science, data assimilation and inverse problems.

Research interests: Numerical linear algebra, matrix theory, applications, inverse problems, image processing, data assimilation, iterative methods for eigenvalue problems and linear systems, Krylov subspace methods and preconditioners, model order reduction, low-rank approximation.

For more recent information visit the pages of our group, publications and teaching.

Important information, in particular events of the SFB 1294 on Data Assimilation can be found here.
