Dr Sebastian Hoenig 

Personal homepage

Dr Sebastian Hoenig graduated (Dipl.-Phys.) from the University of Heidelberg and received his PhD in astronomy from the University of Bonn and the Max-Planck-Institute for Radioastronomy. Following postdoctoral fellowships at the Max Planck Institute, the University of California Santa Barbara, and the University of Copenhagen, Sebastian joined the University of Southampton in 2014 as a Lecturer and Marie Curie fellow. He is now an Associate Professor in the Astronomy Group. 

Sebastian's research focuses on dust in supermassive black holes and involves high-angular resolution observations, 3D radiative transfer modelling (CAT3D), radiation hydrodynamic simulations and time series analysis. His research group is supported by the European Research Council, the European Commission's Research Executive Agency, and the Science & Technology Facilities Council (STFC). Sebastian serves as Deputy Director of the Centre for Doctoral Training in Data Intensive Science (DISCnet) as well as President of the European Interferometry Initiative (EII; http://www.european-interferometry.eu). He is the School's REF champion for the upcoming Research Excellence Framework 2021.
