The Instituto de Física Teórica (IFT, Madrid, Spain) invites applications for a PhD position (predoctoral contract) in gravitational-wave data analysis, funded through the FPI-UAM 2026 program. The position is funded until the successful completion of the PhD, for a maximum duration of four years. The successful candidate will contribute to gravitational-wave science within the LIGO-Virgo-KAGRA (LVK) Collaboration and help prepare for future observations with the Laser Interferometer Space Antenna (LISA). The project combines advanced computational methods, statistics, gravitational-wave astronomy, cosmology, and potentially machine-learning techniques.
Application deadline: 27 September 2026
