The SF2A board has awarded the 2023 young researcher prize to Laure Ciesla from the LAM. Laure Ciesla has been a researcher at the LAM since 2018. Her research focuses on the evolution of galaxies, guessing their history by using their spectral energy distribution and modelling it with the CIGALE code, in which she integrates, for example, the emission of supermassive black holes at the centre of galaxies, or is interested in the contribution of artificial intelligence to this subject. She is very involved in the PRIMA project (Probe far-infrared mission for Astrophysics), under discussion between NASA and CNES. She is also co-leader of the GECO team, and has organised a meeting at the LAM between young students and women in astrophysics, to fight against gender bias.
