My research lies at the intersection of high-level mathematics and data sciences. I explore mathematical properties of advanced processing tools for the reconstruction and the synthesis of naturally-occurring sparse signals. This includes contributions to probability theory (sparse stochastic processes), optimization theory (sparsity-promoting spline reconstruction methods), together with applications in signal processing (inverse problems, segmentation, detection, CNNs). To a larger extent, I expect applied mathematics and advanced signal processing to play a key role in the future developments that will take place in data sciences.

Fields of expertise: Sparsity, random processes, approximation theory, splines, convex optimization, functional analysis, signal and image processing.
