Dr. Stine Gutjahr

studied geophysics at the Freie Universität Berlin where she received her diploma in 2009. For her diploma thesis she performed wavefield separation to the recorded wavefield of an active seismic data set from the San Andreas fault at Parkfield and separately imaged the P-, S- and converted components of the wavefield. Stine finished her PhD in 2015. For her thesis she reprocessed an old industry seismic reflection data set in order to gain additional structural information of the deep crust and upper mantle of the San Andreas fault zone using advanced imaging techniques. Currently she focuses on the detection and location of microseismic events and the processing of refraction seismic data.

Jonas Folesky

received his BSc of Science in Physics from TU-Berlin in 2011. He was a student member of our group until May 2013 when he received his MSc of Science from FU Berlin. Since then he is a doctoral candidate. Jonas is working on the subject of rupture property estimation for events at a microseismic scale. For that he applies, refines and develops different seismic imaging and analysis techniques. His current work is on the application of empirical greens functions and their implications for the analysis of rupture properties at the reservoir scale.
