CRAL/CNRS MEMBERS

Dr. Gil Moretto
Principal Investigator & Coordinator

Dr. Gil Moretto is an Astrophysicist working for CNRS after 2005, following about 10 years based in the US (NOAO/NSF & NSO/NSF, Tucson, Arizona) developing novel instrumentation consistently associated with new technologies for ground-and space-based astronomy. Nowadays, he is the Principal Investigator for the European Innovation Council-funded Pathfinder Live-Mirror (2023–2027) and the FRANCE 2030-funded PEPR Origins/FlexSiMirror (2023–2029) consortia. The Horizon EIC Live-Mirror is supporting the R&D on new rupture technologies to replace classical rigid and heavy optical mirrors with ultra-light, self-correcting dynamic optoelectronic systems consisting of thin optical fire-polished slumped glass sheets actively “live” supported by many-degree-of-freedom force actuators and sensors integrated and miniaturised via additive manufacturing – the Live-Mirror technology. Broadening this cutting-edge technology towards high-frequency domain (kHz), the France2030 PEPR/Origins supports the FlexSiMirror technology towards high-accuracy and lightweight deformable silicon-based mirrors.

Dr. Moretto‘s long-term R&D strategy is the Exo-Life Finder telescope (ELF)– the first telescope facility dedicated to direct imaging and characterisation of telluric exoplanets. Focused on such a challenging astrophysical science case will require cutting-edge technologies: the ultra-light, self-correcting, “Live” Mirrors that maximize their high contrast performance with non-abrasive, additive, 3D-printed novel technology and a very fast FlexSiMirror delivering extreme Adaptive-Optics.

Dr. Francesca Rebasti
Project Manager (WP8)

As an Innovation Project Manager at the Centre National de la Recherche Scientifique (CNRS), Dr. Francesca Rebasti brings over six years of experience in coordinating high-stakes, cross-functional projects within leading research institutions. Her strong academic background, coupled with expertise in administrative and financial management, enables her to align strategic vision with analytical thinking and effective execution.

Dr. Rebasti is deeply committed to supporting interdisciplinary, multinational, and multicultural teams, managing stakeholder expectations, and delivering projects on time and within budget, even in challenging environments. Within the Live-Mirror project, she serves the Principal Investigator by overseeing the Consortium, managing the grant, and leading the coordination and valorisation work package.

Passionate about fostering a culture of continuous improvement, she is dedicated to embracing new challenges and identifying opportunities to drive innovation and excellence in dynamic organizations.

Dr. Éric Thiébaut
WP6 Participant

Dr. Éric Thiébaut is a permanent researcher at the Centre de Recherche Astrophysique de Lyon (CRAL, CNRS/UMR 5574) since 1995. His main research fields are signal processing and inverse problem approaches with applications in astronomy and bio-medical imaging and with main achievements in blind deconvolution, image reconstruction in optical interferometry and from multi-variate data (like hyper spectral imaging from integral field spectrograph), fast wavefront estimation for adaptive optics, optimal detection of exoplanets in high contrast images and of particles indigital holography, statistical approximation and learning, and adaptive optics control. In the Live-Mirror project, he will contribute to the real-time control (RTC) of the adaptive/active optics demonstrator system and to the wavefront sensing algorithms.

Dr. Dipanjana Saha
WP6-7 Participant

Dipanjana completed her Bachelor’s in science in Electronics from University of Calcutta in 2012. Latter she pursued Post B.Sc. Bachelor’s in technology in Optics and Optoelectronics in 2015 and Master’s in technology (also specializing in Optics and Optoelectronics) from University of Calcutta in 2017. After that she worked as a research fellow for two years, first year at TATA Institute of Fundamental Research, India and second year at Chinease University of Hong Kong, Hong Kong.

In 2019, Dipanjana got Marie Sklodowska-Curie grant from the EU and strated her PhD at CNAM, Paris. Dipanjana’s main aspiration was to develop a multiscale measurement traceability to measure material apperance. During PhD she developed a new goniospectrophotometer which can measure BRDF at micro scale.

After that she worked 1.5 years as a R&D Engineer at Ibsen Photonics, Denmark ans now she joined the EIC Live-Mirror project as a postdoctoral fellow.

Eng. Clément Schotte
WP6-7 Participant

Clément Schotte is study engineer with a master’s degree in physics and instrumentation.

For years he has have been working on projects at CRAL or LMA, building machines like an ion beam polisher and developing software from scripts to drivers and graphical user interfaces.

Today his job at Live Mirror is to assemble different electronical components essential to the operating, testing and validation of the deformable mirrors, and to develop software to make them work as smoothly as possible for the rest of the team.

Dr. Kritsadi Thetpraphi

WP4-5 Participant (External Collaborator)

As a senior researcher with a PhD in materials science specializing in ferroelectric materials, particularly electroactive polymers (EAPs), Dr. Thetpraphi’s role in the Live-Mirror project is crucial for the selection and optimization of materials to meet the project’s application requirements. The innovative Live-Mirror technology integrates lightweight glass sheets with dynamic optoelectronic systems supported by force actuators and sensors, all thanks to additive manufacturing. As far as EAPs are concerned, these materials are capable of converting electrical energy into mechanical energy, or vice versa, and above all of being 3D-printed. They have provided a diverse set of applications, such as wireless systems, smart homes, biomedical sensors, smart sports, artificial muscles, deformable mirrors in telescopes, and so on. By optimizing the electromechanical properties of these materials and using an organic doped polymer and multilayer structure, Dr. Thetpraphi contributes significantly to the development of high-quality adaptive optical mirror systems for ground- and space-based telescopes.

Dr. Vincent Bruyère

WP4-5 Participant (External Collaborator)

After completing a PhD in numerical modeling of lubricated contacts in the National Institute of Applied Science (Lyon), Vincent pursued a postdoctoral research position focused on laser welding modeling in the Atomic Energy and Alternative Energies Commission. He is currently the CTO at SIMTEC, where he oversees innovative projects in the field of engineering and research simulations. In his current role, he plays a key part in the “EIC Live-Mirror Consortium” project as an external collaborator, focusing on the modeling of piezoelectric actuators and their impact on mirror deformations. This project merges precision engineering with advanced simulations, showcasing his expertise in both theoretical and applied modeling techniques.
