Associate professor in Astronomy & Astrophysics
My name is Julien Girard, and I am an associate professor at LIRA at the Observatoire de Paris and Université Paris Cité. 
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.
I am also a radio interferometrist, specializing in synthetic aperture imaging applied to large low-frequency radio telescopes (LOFAR, NenuFAR).
I participated in the definition and optimization of the architecture of the NenuFAR instrument (Research Infrastructure), now in operation at the Nançay Radio Astronomy Observatory.
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.
I also contribute to the European EXTRACT project and, as part of the ECLAT joint laboratory, to defining solutions for the future French SKA Regional Centre.
