Jonas received his BSc of Science in Physics from TU-Berlin in 2011. He was a student member of our Group until 2013 when he received his MSc of Science at Freie Universität Berlin after which he became a doctoral candidate. In the following years he conducted research on earthquake rupture imaging methodology and multiple case studies. He published papers on back projection imaging, p-wave polarization based imaging, and empirical Green's function based rupture analysis. In 2018 Jonas received his PhD from Freie Universität Berlin and he works now as a postdoctoral researcher in the Seismology Group. His current research focus is on earthquake rupture processes, rupture imaging methods, and earthquake source physics.
