Tobías I. Liaudat
I am a staff research scientist at the Institute of research into the fundamental laws of the Universe (IRFU) in the (CEA) Saclay near Paris.
My research lies at the crossroads of signal processing, statistics, machine learning and physics. I am particularly interested in leveraging recent artificial intelligence techniques and developing new methodologies that can be applied to inverse problems in a wide range of scientific applications like astronomy, cosmology and radio interferometry.
I was a postdoctoral research fellow at the Mullard Space Science Laboratory (MSSL), in the University College London (UCL) Space and Climate department and the Computer Science (CS) department, where I am working with Prof. Jason McEwen, Prof. Marcelo Pereyra and Prof. Marta Betcke. Before that, I completed my PhD at the CosmoStat Laboratory at the CEA Saclay near Paris under the supervision of Dr. Jean-Luc Starck and Dr. Martin Kilbinger.
I am a member of the European Space Agengy (ESA) Euclid satellite science consortium, the Laser Interferometer Space Antenna (LISA) consortium, the James Webb Space Telescope (JWST) COSMOS-Web survey, and the UNIONS survey science collaboration.
