I am working in the field of astrophysical fluid dynamics. I am particularly interested in the magnetic field generation from turbulent motions with applications to the Sun and stars, accretion discs, galaxies, and the early Universe. I have been working on accretion disc turbulence to show that the magneto-rotational and dynamo instabilities lead to a sustained doubly-positive feedback. Recently, I have contributed to clarifying the long-standing question of the suppression of the dynamo effect in generating large-scale fields. I am also responsible for the maintenance of the Pencil Code, which is a public domain code (https://github.com/pencil-code) for astrophysical fluid dynamics that is well suited for large clusters with distributed memory.
