Andreas Fichtner PhD

Andreas Fichtner is a Professor of Seismology and Wave Physics at ETH Zurich. In January 2010, he received his PhD from the University of Munich for his work on Full Seismic Waveform Inversion for Structural and Source Parameterscall_made. During his postdoc at Utrecht University, Andreas worked on the development of resolution analysis and multi-scale methods for seismic waveform inversion.

His research foci are on seismic tomography and fibre-optic sensing. To image the deep interior of the Earth, his team develops and applies novel techniques for numerical wave propagation, highly specialised non-linear optimisation techniques, and methods for uncertainty quantification in large-scale inverse problems. They deploy fibre-optic cables of several kilometres length in densely populated cities and on volcanoes and glaciers. Using laser interferometry, these cables become seismic sensors that provide information about Earth's structure and seismicity with unprecedented resolution. In addition to these core areas of expertise, He is working on and publishing in high-performance computing, medical ultrasound imaging, effective media and metamaterial design, non-destructive testing, and fibre optics. He is a co-founder and scientific adviser of the ETH Spin-Off Mondaiccall_made which provides solutions for full-waveform modelling and inversion to academia, industry and national labs.
