PhD in Observational Cosmology at ICE-Barcelona

Location: Institute of Space Sciences (ICE-CSIC), Barcelona, Spain.

The “Observational Cosmology and Extragalactic Astrophysics” group at the Institute of Space Sciences (ICE, CSIC; invites applications for one PhD position to start as early as September 2026. The candidate will work under the supervision of Dr. Martin Crocce and Dr. Matteo Zennaro.

Responsibilities: The selected candidate is expected to research aspects of galaxy clustering and weak gravitational lensing, including their modeling through analytic theory or simulations and the cosmological inference. The student will contribute to the scientific exploitation of the ESA Euclid mission ( and other leading galaxy surveys, such as DESI, Rubin/LSST, and DES.

Group Overview: The host cosmology group covers a broad range of aspects in Observational Cosmology and the study of Large-Scale Structure, spanning theory modeling, production of simulations and mock catalogues, development of tools based on machine-learning and neural networks, and real data analysis. The group consists of 6 senior members, 4 research fellows, several postdocs and PhDs, and has access to computing facilities like the Marenostrum supercomputer, ICE cluster, PIC and CosmoHUB.

Qualifications: Applicants should have the academic credentials to enroll in the PhD program at the Autonomous University of Barcelona (UAB) during the 2026/2027 academic year. This typically requires having completed, or being close to completing, an MSc (Master) degree or equivalent. The position is for three years, with the possibility of an additional year extension. Salary and benefits are in line with other PhD positions in Spanish institutions. We encourage applicants from traditionally under‑represented groups in science, physics, and astronomy.

Application Details: Interested candidates should submit a short CV, academic transcripts, and one or two reference letters to Dr. Martin Crocce (Ver el correo electrónico en click.appcast.io) and Dr. Matteo Zennaro (Ver el correo electrónico en click.appcast.io). Use the email subject line “COSMOPHD” followed by the applicant’s surname(s). We encourage early applications before May 8, 2026, but the position will remain open until filled.
