The Institute of Cosmos Sciences of the University of Barcelona (ICCUB) invites applications for a 3-year Postdoctoral position in gravitational wave astronomy, as part of its current call for two postdoctoral positions and one ICCUB Postdoctoral Fellowship, offered under the framework of its Unit of Excellence Maria de Maeztu. Application deadline: November 30th, 2025.

The successful candidate will lead projects spanning both theoretical and data analysis aspects of gravitational wave science. Research topics may include, but not be limited to parameter estimation, gravitational lensing, numerical relativity simulations, detector characterization, mock data generation, neutron star asteroseismology, magnetohydrodynamic modeling of neutron stars and multimessenger signals, stellar/BH dynamics, tests of general relativity, relations to high energy and nuclear physics and connections to holography. The ICCUB is a member of the LVK Collaboration, the Einstein Telescope Collaboration and is contributing to the LISA mission on theoretical models, computing and instrumentation activities. We are also part of the Spanish RedONGRA network (Red Nacional en Ondas Gravitacionales), which fosters national collaboration in gravitational wave research. In addition, we are actively participating in surveys (ESA-Gaia, Weave, SDSS-IV) and EM follow-up missions at various wavelengths (BlackGEM, MAGIC and LSST), which allow scientists at the ICCUB (https://icc.ub.edu/research/gravitational-waves) to build an end-to-end understanding of all steps leading to GW sources. Prior research experience in gravitational wave data analysis is preferred, but not strictly required. Experience with large-scale computation, Bayesian methods, and/or machine learning/AI is considered a plus.

These positions are part of a dynamic and interdisciplinary research environment at one of Europe’s leading centers in cosmology, astrophysics, and particle physics. The Institute of Cosmos Sciences (ICCUB) at the University of Barcelona, established in 2006, focuses on cosmology, astrophysics, particle physics, quantum physics, and nuclear physics. With over 70 scientists, 20 engineers, and 90 postdoctoral researchers and PhD students (35% international), ICCUB collaborates internationally on projects like Gaia, LHCb, Virgo, MAGIC, CTA, and DESI. It also has an Advanced Technology Unit supporting experimental research requiring cutting-edge technology.

Requirements:

Applicants must hold a PhD in Physics, Astrophysics, or a closely related field by the start date of the contract, approximately in October 2026. We are looking for motivated researchers with a strong track record and a collaborative spirit.

Employment Terms:

• Duration: up to 3 years
• Start Date: Preferably by Fall 2026 (flexibility possible for parental or special circumstances)
• Salary:
• Maria de Maeztu Postdoctoral Positions: Approx. 36.360€/year (gross), including full social security and public healthcare coverage for the researcher, spouse or registered partner and children
