Hoël Seillé

Research Scientist in Geophysics

Geophysicist with a solid expertise using the magnetotelluric method (MT). My current research focuses on the development and application of geophysical data modelling workflows and algorithms, emphasising on the integration of various geoscientific data using probabilistic approaches.

Prior to joining the Deep Earth Imaging FSP Platform, I received a PhD from the University of Barcelona, where my research consisted in characterizing the lithospherical structure of several orogens in the Iberian Peninsula using magnetotelluric data. I also worked as a Geophysicist in the industry, in charge of geothermal exploration projects using multi-physics approaches.

I am part of the Deep Earth Imaging Future Science Platform and the CSIRO Mineral Resources EM & Seismic team.
