ℹ️ About Me

I am a postdoctoral researcher at the University of Oslo, Norway, working with the Digital Signal Processing and Image Analysis (DSB) research group. I develop physics-based inverse methods for imaging applications across geophysics and medical ultrasound.

My work sits at the intersection of applied mathematics, geophysics, signal processing, and medical imaging. Previously, I was a postdoctoral researcher with the IDEFIX team in France, a joint research group between Inria Saclay Centre and EDF R&D. I obtained my PhD in Applied Mathematics from the University of Caen Normandy, France.

🧑‍🔬 Research Interests

🧑‍🔬 Current Projects

Ongoing work spans medical elastography, seismic and sonar imaging, with a shared focus on practical, physics-based inversion methods.

Sonar for Seafloor Imaging

2026-2027

Secondment: Kongsberg Discovery, as part of the DSTrain postdoctoral project

This collaboration with Kongsberg Discovery focuses on sonar data for subseafloor imaging. The work connects wave-based inversion methods with real-world marine acoustic data.

Seismic Imaging of the Dam-Rock Foundation Interface

2022-2027

Funding: Plan France Relance (2022-2024), followed by AURORA mobility funding (2026-2027)

Three-dimensional seismic imaging of a dam-rock foundation interface

Initiated with the IDEFIX team as a collaboration between INRIA and EDF R&D, this project addresses interface imaging challenges at electricity production sites.

  • Targets high-resolution imaging of the dam-rock foundation interface.
  • Combines shape optimization with Full-Waveform Inversion for non-invasive seismic data.
  • Extends methodology to 3D settings and more realistic operational forward models.

The AURORA programme is a Norway-France mobility scheme that supports researcher exchanges, joint workshops, and collaboration building between partner institutions. The supported project is titled Full-Waveform Inversion for Dam Safety.
