I am a researcher in applied mathematics in the
Inria project-team Makutu,
at the University of Pau et des Pays de l'Adour.
My research is centered on inverse wave problems for imaging,
where the objective is to recover the physical properties of
a medium from the observation of wave propagation.
My research has an emphasis on time-harmonic wave equations,
seismic imaging, and helioseismology.
I develop and maintain the dedicated open-source parallel software
hawen
used for large-scale applications.
