Torsten Enßlin is head of the Information Field Theory group at the the Max-Planck-Institute for Astrophysics. His research focuses on the application of IFT to problems in cosmology, such as the fluctuations of the cosmic microwave background or the large-scale structure of the cosmic matter distribution. He and his group are also working on galactic cartography, in particular on special-purpose IFT methods to better imagine relativistic particles and magnetic fields, and even to tomographically reconstruct their distribution within the Milky Way.
