About me
I graduated from ELISA Aerospace engineering school in 2017, specialising in rockets and space systems. I then joined the Institut d'Astrophysique Spatiale (IAS) as a research engineer, where I developed my expertise in sub-Kelvin cryogenics for space instrumentation. I subsequently completed a PhD at IAS / Université Paris-Saclay (defended March 2023), focused on the development of a Closed-Cycle Dilution Refrigerator (CCDR) for future cosmological space missions. I am now a postdoctoral researcher at IAS.
My research sits at the intersection of sub-Kelvin cryogenics, ultra-sensitive detector physics, and space instrumentation for CMB experiments. I lead the development of the CCDR — a space-qualifiable system continuously cooling detectors to 100 mK — and of DRACuLA, a unique European facility designed to characterise cryogenic detectors (KIDs, TESs, bolometers) under realistic space radiation conditions. I contribute to several flagship missions: LiteBIRD (JAXA, launch ~2033), PRIMA/PRIMAger (NASA, launch ~2032), and BISOU/FOSSIL (CNES/ESA), with responsibilities spanning instrument design, thermal architecture, and irradiation campaigns.
The broader goal of my work is to enable the next generation of CMB observations — in particular the first detection of primordial B-mode polarisation and µ/y spectral distortions — opening a direct observational window on the physics of the early Universe. To this end, I combine thermo-hydrodynamic modelling, experimental qualification, and international collaborations across Europe, Japan, and the United States.

Ongoing
Under development space-qualifiable dilution refrigerator continuously cooling detector focal planes to 100 mK — successor to the open-cycle system flown on Planck-HFI. My work spans thermo-hydrodynamic modelling, thermo-mechanical structural design, material property characterisation at sub-Kelvin temperatures (with CEA-DSBT and IRAP), and critical subsystems including the boiler and fountain pump.
Since 2017The only European facility capable of simultaneously cooling next-generation cryogenic detectors to their operating temperature and irradiating them with energetic particles. Deployable in front of particle accelerators, it characterises detector response to cosmic-ray impacts and estimates performance degradation after years of space exposure. Three campaigns completed: bolometers (2022), TES/LiteBIRD (2024), KID/PRIMA (2025).
Since 2021Active member of the Cosmic Rays – High Frequency Telescope working group. Led the irradiation campaign of NIST TES prototypes at TANDEM/IJCLab (Orsay, 2024) with INFN Pisa, characterising glitch signatures from 18 and 22 MeV protons. Also contributing to the thermal conductivity characterisation of CFRP focal plane support structures from 100 mK to 20 K.
Since 2023In charge or the KID irradiation campaign at SRON Groningen. Led DRACuLA campaign #3 at the PARTREC accelerator (Netherlands, September 2025), irradiating KID prototypes at 120 mK to simulate ~10 years of cosmic-ray exposure at L2. Also characterised LiteBIRD bi-stage SQUIDs and Athena X-IFU LC resonators during the same campaign.
Since 2024Stratospheric balloon experiment targeting CMB spectral y-distortions (Phase A). Responsible for the thermal architecture of the flight instrument and cryostat, the development of the ground qualification cryostat for the Fourier Transform Spectrometer prototype, and contributions to the internal reference (blackbody) design.
Since 2023Space evolution of BISOU, targeting absolute spectroscopy of the sky from 30 to 2000 GHz to improve COBE/FIRAS constraints by ~3 orders of magnitude. Within this ~260-member international collaboration (19 countries). As a main contributor, I coordinate the thermo-mechanical study of the full payload and cryogenic interfaces, leading the dedicated working group.
Since 2024Past
Contributed to the preparation and execution of the third and final scientific flight of the PILOT stratospheric balloon experiment (polarimetric study of galactic dust). Responsible for photometer logistics, cryogenics, and vacuum system management during the 50-day campaign at Timmins, Canada, culminating in a successful 38-hour flight in August 2019.
