Dr. Torsten Enßlin is the head of the MPA Planck Analysis Centre (MPAC), which hosts the German participation in the Planck surveyor satellite mission. He holds a doctoral degree in astronomy from Bonn University (1999) for his theoretical work on relativistic particles and magnetic fields in galaxy clusters. In 1999, he was working at Toronto University on radio astronomical observations of galaxy clusters, and moved to the MPA for theoretical research. In 2003, he accepted the position as the head of MPAC on a tenure-track basis and became a permanent staff scientist in 2006. For the Planck Project, he supervises the development of software infrastructure, namely the Planck-Simulation package, a scientific workflow engine (the ProC), and a data management component interfaced with it. Furthermore, he is a member of the German Long Wavelength (GLOW) Consortium, and participates in the Magnetism Key Science Project of LOFAR. His current scientific work embraces investigations of energetic particles and magnetic fields in large-scale structures, theoretical cosmology, and information field theory. The latter is the application of information theory to problems of image reconstruction. It has been successfully applied to cosmography, the mapping of the large-scale structure as traced by galaxies, analysis of the cosmic microwave background, and radio astronomy.
