Unravelling the electrical structure of the mantle with ionospheric, magnetospheric and oceanic EM signals
ETH Zurich, Switzerland
Alexander Grayver is a Senior Scientist in the Earth and Planetary Magnetism group at the Institute of Geophysica, ETH Zurich. He obtained a PhD degree in 2013 from the Department of Earth Sciences, Free University of Berlin. Prior to coming to ETH Zurich, he worked as a Research Assistant at the Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences from 2010 to 2014. His research interests are centered around PDE-constrained optimization methods in the context of non-linear inverse problems, numerical modeling of EM induction phenomena from local to global scales and application of machine learning methods to ground and satellite geophysical data. He tries to study the electrical structure of subsurface at different scales, trying to illuminate volcanic systems and geothermal fields, constrain temperature and water content of the upper mantle and transition zone and integrate the electrical conductivity with other geophysical observables in order to build a self-consistent model of Earth’s interior.
East African Rift from an electromagnetic perspective: Geodynamics, Evolution, Resources and Geothermics
Sophie Hautot is CEO of Imagir sarl, based near Brest, France. She received her PhD in geophysics in 1999 from the University of Brest. From 1999 to 2010, she was associate researcher at the University of Edinburgh and then Brest. Her research focuses on magnetotellurics (MT), with the development of new interpretation tools (3D inversion) and application to crustal studies, particularly the structure of the East-African Rift. In 2010, she left the University of Brest and created Imagir, a company specialised in magnetotellurics where she applies her latest developments to the 3D inversion of large MT data sets collected for geothermal and oil&gas exploration and for research projects.
