I work in the field of low-frequency radio (between 10 MHz and 100 MHz) to study radio emissions in planetary and exoplanetary systems, signatures of plasma activity and electron populations in the environment of these planets.<\/p>\n\n\n\n

I am also a radio interferometrist, specializing in synthetic aperture imaging applied to large low-frequency radio telescopes (LOFAR<\/strong>, NenuFAR<\/strong>).<\/p>\n\n\n\n

I participated in the definition and optimization of the architecture of the NenuFAR<\/strong><\/a> instrument (Research Infrastructure), now in operation at the Nan\u00e7ay Radio Astronomy Observatory<\/strong><\/a>.<\/p>\n\n\n\n

My research activities also focus on digital signal processing, inverse problem solving, electromagnetic simulation and the application of deep learning methods to imaging and massive data processing.<\/p>\n\n\n\n

I also contribute to the European EXTRACT<\/strong><\/a> project and, as part of the ECLAT<\/strong><\/a> joint laboratory, to defining solutions for the future French SKA Regional Centre<\/strong>.<\/p>\n\n\n\n
