Das Researcher in Imagery and Multi-scale Geophysical Characterization

**Who are we?**

**What will your mission be?**

You will use data acquired with submarine cables (distributed measurements on optical fibers) to develop methods for the processing and the inversion of DAS (Distributed Acoustic Sensing) data, with the goal to obtain high-resolution images of geological structures at multiple scales. To do this, you will exploit massive datasets, using state-of-the-art geophysical methods such as full waveform inversion (FWI) and innovative techniques based on artificial intelligence (AI). Your research activities will support the institute's efforts on current and future projects using submarine cables for deep-sea exploration (France 2030), as well as on geophysical challenges associated with marine renewable energy. By integrating DAS observations with conventional data, such as seabed seismometers (OBS), you will contribute to the high-resolution characterization of active geological processes in the marine environment, as well as to the development and exploitation of DAS technology for monitoring the integrity of subsea infrastructures.

**What will your activities be?**
- You will have a demonstrated expertise in the analysis and interpretation of geophysical data (seismology) for improving imaging and physical characterization of the subseafloor.
- You bring skills in processing voluminous datasets using artificial intelligence (machine learning, deep learning, etc....).
- You will work with the Datarmor team in Ifremer's IRSI computing department to develop parallel computing and/or GPU optimization for geophysical data analysis.
- You will supervise students at all levels as well as post-docs; to write publications and respond to projects’ calls
- You will contribute to the development of a culture of innovation within the research unit by taking an interest in potential industrial transfers and the economic valorization of its activities, notably via Ifremer's internal tools (e.g., Institut Carnot MERS).

**Collaborative work environment**

**How are your activities organised?**
- Activity rate: 100%
- Position based at Ifremer Plouzané, with possible travel for field missions. Offshore and/or coastal sea campaigns possible.
- Open-ended contract - Position vacant.

**Who are you?**
- Strong skills in high-performance computing and artificial intelligence for massive data analysis and inversion for seismic imaging, using modern geophysical techniques such as full waveform inversion (FWI).
- Initial training: PhD in geophysics and/or physics with a specialization in AI.
- Post-doctoral experience will be appreciated.
- Experience in a company or in partnership projects is an advantage for the position.

**You have the following skills, knowledge and experience**:

- Strong experience in information and signal processing
- Experience in data analysis, particularly of large datasets
- Experience in inverse methods applied to seismic imaging
- Research experience demonstrating ability to publish research work
- Advanced knowledge of programming/scripting languages
- Preferably knowledge/expertise of distributed fiber sensing techniques

**You have the following qualities**:

- Dynamic, highly motivated
- Team player, interested in working in a team, particularly a multidisciplinary one
- Desire to develop new technologies and techniques for geosciences in marine environments
- Ability to take part in campaigns at sea or in the field

**What are your benefits?**
- We have a teleworking agreement and our staff have 12 comp time days and supra statutory leave.
- We allocate a significant budget to developing skills, through individual or collective training actions.
- We have a CSR policy inspired by the purposes of the institute (sustainable mobility allowance, etc.)

**What are the next steps?**
- Initial pre-qualification via video conference or phone call.
- Interview with technical and HR partner
- Interview with the supervising team

Qui sommes nous ?

**Join Ifremer, an ally of planetary well-being, to gain a better understanding of and better protection for the ocean.**

From the abyss to the surface, from the coast to the open sea, Ifremer is the French research institute that is wholly dedicated to the Ocean. Its teams carry out research, innovate and produce expert reports to protect the ocean, exploit its resources in a responsible manner and shares marine data.

Ifremer contributes its scientific expertise to throw light on public policies and develops solutions drawn from the ocean to meet the challenges of the ecological transition. Ifremer is the operator of France’s oceanographic fleet with its shipbuilding subsidiary Genavir, and imagines, designs and deploys leading edge technological means to solve the ocean’s mysteries.

Join our teams, made up of 1500 scientists and research support staff, present all along the coastal areas of France and French overseas territories.
