About the Instructor
Serge A. Shapiro has been Professor of Geophysics at the Freie Universität Berlin, Germany since 1999, and since 2004, Director of the PHASE (PHysics and Application of Seismic Emission) university consortium project. From 2001 till 2008 he was one of Coordinator of the German Continental Deep Drilling Program (KTB). He was one of PIs of the 3rd KTB long-term fluid-induced seismicity experiment. His research interests include seismogenic processes, wave phenomena, exploration seismology, and rock physics. He received the SEG Virgil Kauffman Gold Medal in 2013 for his pioneering research on fluid-induced seismicity and rock physics, and in 2004 was elected a Fellow of The Institute of Physics (UK).
