Research interests
My research is in observational cosmology and in gravitational lensing in all regimes: strong, weak, micro and milli. I contributed to develop the field of time delay cosmography with strongly lensed quasars, to measure the Hubble constant and address the so-called Hubble tension between early and late Universe measurements. I was granted and ERC Advanced Grant in 2018, COSMICLENS, specifically on time delay cosmography.
I'm also a builder member of the ESA-NASA Euclid mission, in which I've been involved from the very beginning. In Euclid, I'm the current lead of the strong lensing science working group. I'm active in the Rubin-LSST time domain survey and is part of the Spanish-led ESA-ARRAKIHS mission to study the nature of Dark Matter with ultra-deep observations of local galaxies.
A significant part of my research is also in pure signal processing, and in particular image deconvolution and morpho-spectral decomposition with sparse regularization and machine learning techniques.
