I work as a research scientist (akademischer Rat) at the Argelander Institute for Astronomy at Bonn University, where I am a member of the stellar physics group. I started working here in September 2009 after three years at the Canadian Institute for Theoretical Astrophysics (CITA) in Toronto. Before that I did my PhD at the Max Planck Institute for Astrophysics near Munich.

My research focusses on fluid dynamics and magnetohydrodynamics in various astrophysical contexts such as star formation, high-mass stars, white dwarfs, neutron stars and the diffuse interstellar and intergalactic media. Click here to read more about my research interests..

Here you can look at my travel plans and those of the other group members.

Students

I am currently supervising two students:

• PhD student Luis Boldt is working on accretion of material onto neutron stars and on the effect of magnetic fields on differential rotation in stars.

• Masters student Juan Camilo Ibañez is working on MHD instabilities in stars.
