Research Interests

My thesis title is Sparse Semi-Parametric Recovery of Astronomical Radio-Images. Its goal is to develop new signal processing tools to reconstruct image acquired from radio telescopes. The main topics that I work on are Image Processing, Inverse Problems, Convex Optimization and Deep Learning.

Shape information contained in galaxy images is important in various domains of astrophysics such as Cosmology and Galaxy Evolution. During my PhD, I developed a shape constraint that allows to improve the reconstruction of galaxy images and the recovery of its physical information. As a proof of concept, I developed a sparse recovery algorithm and added the shape constraint to it. For this purpose, I generated a parametric dataset of optical galaxy images. Then I extended the shape constraint to Deep Learning and tested it by generating two realistic dataset containing more than 50,000 images each. The first dataset has optical images and the second one has MeerKAT-like radio images, which allowed us to test the Deep Learning methods we used and improved, for the first time, on radio data.
