Research Profile

My main research is focusing on the back-arc basin and the currently active island arc in the Mariana subduction zone in the north-western Pacific. I am fascinated by these geologic settings, because they are regarded as highly dynamic regions encompassing the oceanic and continental domain. While island arcs are considered as prime location for the growth of continental crust, back-arc basins play a major role in the opening and closure of ocean gateways. To gain information about the structures in the crust and upper mantle, I use ocean bottom seismometer (OBS) that record seismic signals on the seafloor and analyse them by generating a seismic tomography.

I am a marine geophysicist and sailed in five sea-going expeditions and stayed 189 days at sea, collecting geophysical data from the Atlantic, Pacific Ocean and some marginal seas. Furthermore, I gained 107 days of terrestrial field experiences using a broad range of geophysical methods, providing additional understanding for other geophysical methods and insights into continental aspects.
