My name is Magnus Vilhelm Persson and I am a Post Doctoral Researcher (Post Doc) in Wouter Vlemming's group at Onsala Space Observatory (Chalmers University of Technology). My research focuses on high-angular resolution ground-based observations towards protostars. I handed in my thesis at Copenhagen University April 5, 2013, and successfully defended it June 13, 2013. I am working primarily with data from the Plateau de Bure Interferometer (PdBI), Sub-millimeter Array (SMA) and of course the Atacama Large (sub)Millimeter Array (ALMA), but also with single-dish data from the IRAM-30m, the Atacama Pathfinder EXperiment (APEX) and the Herschel Space Observatory telescopes.
