Two PhD positions in astronomical instrumentation for Exoplanet imaging

Paris Observatory is seeking candidates for 2 PhD scholarships starting in Fall 2026.

Direct imaging of exoplanets is one of the most exciting and rapidly evolving fields in modern astronomy. By capturing light directly from exoplanets, we can already study the atmospheres of large gas giants, but the ultimate goal of this method is to access earth-like planets to search for bio-signatures. However, the extreme brightness of host stars compared to their planets makes this task extraordinarily challenging. Coronagraphs are optical instruments designed specifically for this challenge: to suppress starlight to detect the faint exoplanet signal.

The next generation of giant telescopes, such as the European Extremely Large Telescope in Chile and NASA’s Habitable Worlds Observatory, will rely on these techniques to image Earth-like planets in the habitable zones of nearby stars. Both missions require new coronagraphic techniques to achieve the extreme contrast necessary to detect these faint worlds. The ECHOES project (PI: Mazoyer), funded by the European Research Council (ERC), aims to greatly advance exoplanet imaging by developing groundbreaking coronagraphic techniques for these missions. As part of the ERC project ECHOES, these 2 PhDs are already fully funded.

The successful candidates will be part of the exoplanet team at LIRA / Paris Observatory - PSL. Our team is committed to fostering a diverse work environment by actively recruiting individuals of all genders and nationalities. In Paris observatory, arguably the world oldest institution for astronomical research, our team is one of the largest and most dynamic exoplanet research groups in Europe, in particular for direct imaging. The project provides a collaborative network, engaging with leading experts in optics, astrophysics, and machine learning from institutions such as ESO, NASA, and ONERA. PhDs in astronomical instrumentation for future missions sits at the intersection of engineering and astrophysics. It is a great opportunity for applicants interested in starting a high impact academic career but also open exciting job prospects in space agencies or industries.
