The Minds Behind PSFCraft¶

Principal Investigators:¶

Lucas Saunière¶

Lucas is a PhD student at CPPM. He is working on the development of a physical model of the NISP’s instrument response. He is co-supervised by William Gillard and Stéphanie Escoffier.

The Team:¶

William Gillard¶

William is assistant professor at the Aix-Marseille University. He is a full-time member of the Euclid consortium and is the NISP instrument scientist for the NISP spectroscopic channel and member of the coordination group within the Instrument Operation Team. As part of his duty, he has the responsibility to provide NISP spectroscopic calibration product form the ground data. This duty has led him to define the NISP ground test plan and to take the lead of the analysis of the dataset collected during the ground test campaigns. He is also member of the ANR DeepDip, started two years ago, which aim at calibrating photometric redshift by mean of machine learning technic. William Gillard will lead the team toward the development of a physical model of the NISP’s instrument response.

Julien Zoubian¶

Julien is Research Engineer and permanent staff of CPPM. He is a full-time member of the Euclid consortium as NISP Instrument Model Owner (IMO). He is an expert on the slit-less spectroscopy simulation and started the development of the NISP sky simulator TIPS which is now under the responsibility of the SIMulation Organisation-Unit (OU-SIM) within the Euclid consortium. Additionally, Julien Zoubian has an expertise in modelling and machine learning, and its implementation on computing farms, on the CPPM GPU platform as well as on national platforms such as the CC-IN2P3 and the Jean-Zay supercomputer. He is a member of the scientific committee of the AstroInfo thematic school of CNRS and member of the ANR DEEPDIP project.
