Post-doc position in seismology : new methodologies in data analysis
Offer Description
We are seeking a candidate for a project of data exploration in seismology. Large amounts of seismological data are available and the various tools developed with the rise of machine learning open new possibilities to track down signatures of physical processes at work in the depths of the Earth.
The classical data product in seismology is the event catalog. Considerable progress has recently been made in detection, both by implementing weak event detection through network response (Beaucé et al., 2022) and by developing statistical detectors robust to noise (El Bouch et al., 2022). In addition, an advanced data representation (ScatNet: Seydoux et al., 2020) gives access to new continuous characteristics of the signals that can be related to changes in the environment (e.g. Steinmann, 2022). These approaches will be applied to seismic and geodetic data sets.
The funding is for an initial one-year contract, renewable for a second year.
The work is part of the activities of MIAI (Multidisciplinary Institute in Artificial Intelligence of Université Grenoble Alpes) and of ERC AdG F-IMAGE.
