Christian Sippl

Dr. Christian Sippl (1984) works as a researcher at the Institute of Geophysics since April 2019. His main research focus is the tectonics and geodynamics of convergent margins, investigated with a variety of seismological means. Recently, most of his work has been dedicated to the structure of the Chilean subduction zone.

Christian obtained his Ph.D. degree in 2013 at Free University of Berlin and GFZ Potsdam, studying earthquakes and tectonics in the Pamir and Hindu Kush mountains of Tajikistan, Kyrgyzstan and Afghanistan. After a 3-year postdoc at the Australian National University in Canberra, Australia, where he studied the structure of a Proterozoic orogen in the southwest of the continent, he returned to GFZ Potsdam for a two-year postdoc from 2016-2018. There, he started working on the Chilean subduction zone, which continues to be one of his main research areas today.
