The doctoral fellowship programme INPhINIT ”la Caixa” is devoted to attracting talented Early-Stage Researchers—of any nationality—who wish to pursue doctoral studies in Spanish or Portuguese territory. Sponsored by ”la Caixa” Foundation, it is aimed at supporting the best scientific talent and fostering innovative and high-quality research in Spain and Portugal by recruiting outstanding international students and offering them an attractive and competitive environment for conducting research of excellence.
The Institute of Cosmos Sciences of the University of Barcelona is a research centre accredited with the Spanish Seal of Excellence María de Maeztu in 2020, the perfect place to carry out your PhD project through an INPhINIT Incoming fellowship.
The Gaia mission of ESA is providing extensive catalogues with an unprecedented amount of data of extremely high precision. The recent third release (DR3), with about 1.8 billion stars, includes more radial velocities and astrophysical parameters, constituting the ideal dataset to study the structure and dynamics of the Milky Way (MW).
The Gaia data has been revolutionary in several aspects about our Galaxy. Firstly, Gaia has unveiled a large list of new stellar clusters and has characterized better the known ones. These stellar aggregates trace the young and intermediate-age component of the Galaxy. Secondly, the measurements of the phase space coordinates of many stars in the MW disc probe the forces acting on the Galaxy. Phase space substructures discovered by Gaia show that the MW is still recovering from past perturbations probably caused by the approaches of the Sagittarius dwarf Galaxy, while it may also be affected by the forces from the central bar and the spiral arms.
Disentangling the effects of these processes (internal and external) is crucial to uncover the exact history and evolution of the MW. What is the role of each of these mechanisms? Is one of them dominating? Where and in which periods of the MW life? Are these processes interfering with each other? The objective of the project is to establish the impact of the different mechanisms that act on the Galaxy disc including the bar, the spiral arms and the interaction with the Sagittarius dwarf galaxy.
The GaiaUB team (4 staff, 8 postdocs, 4 PhD, and 8 engineers) has a leading role in Gaia at the highest technological, scientific and management levels, as well as in the scientific and technical building of WEAVE. On the technical side, the Gaia group is expert on scientific HPC, Big data, massive catalogue statistics and analysis, and performs research in Galactic fields including dynamics, open clusters and the Large Magellanic Clouds. We have weekly science group meetings and a weekly journal club.
Job position description
In addition to Gaia data from DR3 and DR4 (2025-2026), data from the large spectroscopic surveys from the ground will soon provide kinematic and chemical data for stars that are too faint for Gaia to measure. We aim to explore these new data (Gaia, WEAVE@WHT, 4MOST@VISTA) to study the evolution of our Galaxy.
The student will analyze these new catalogues that will cover regions of the Galaxy never explored before with these large amounts of data and such precision (e.g., end of the bar, outermost parts of the disc, where different processes might be dominating). The student will also explore the whole set of stellar clusters. Most of the clusters have determined ages and can help to date the different effects occurring to the MW disc. In addition, the clusters allow the understanding of the mechanisms of their formation and disruption, and their contribution to the disc of the MW and its chemo-dynamical history.
The PhD will be carried out with the Gaia group at the ICCUB. Our group has long experience in the design, development, operation, archive and data exploitation of the mission. The student will also benefit from the interaction with the software engineering group at the ICCUB Technological Unit in order to develop and utilize Big Data and Data Mining tools to take full advantage of the amount and unique quality of the Gaia data; for this purpose, we will develop data mining algorithms and probabilistic (hierarchical Bayesian) models. The work in the PhD will combine the advanced data analysis and the scientific exploitation of the Gaia data and related surveys. The student will be formed in Data Science and data modelling.
The PhD student will create strong collaborations by being integrated in the international network of the team (e.g., DPAC consortium with 450 scientist and engineers, WEAVE science team, MW-Gaia COST and REG networks).

Working at the Institute of Cosmos Sciences
The Institute of Cosmos Sciences is a research institute of the University of Barcelona. It is an interdisciplinary centre dedicated to fundamental research in the fields of cosmology, astrophysics, and particle physics. In addition, the institute has a strong technology program through its participation in international collaborations in observational astronomy and experimental particle physics.
Moreover, the ICCUB participates in many key international scientific consortia and projects, such as the Large Hadron Collider, the Gaia astrometric space mission, the MAGIC / CTA high-energy astrophysics telescopes, and the Virgo gravitational wave detector, among others. Additional information about the Institute and the University of Barcelona can be found here.
You will be encouraged to contribute and interact with other researchers in the vibrant and international research environment as well as to participate in our outreach initiatives, more information at serviAstro and serviParticules.
As part of the University of Barcelona, the ICCUB is a recipient of the European Commission’s HR Excellence in Research (HRS4R) Award, which recognises, among other achievements, respect for equal opportunities and the capacity to attract talent in a positive working environment that promotes the pursuit of successful research careers. The ICCUB respects the principles of open, transparent, merit-based selection. We strongly encourage women and underrepresented minorities in physical sciences to apply. For additional information please see the Diversity, equity and inclusion Commission.
The ICCUB is located in Barcelona, considered the 8th World's Best Cities 2021: one with near-perfect weather year-round, miles and miles of beaches, iconic parks, striking architecture and colourful neighbourhoods that march to their own beat—artistic, sophisticated, bohemian.

In order to be accepted, candidates must meet the following eligibility requirements:
- Experience: At the call deadline, applicants must be in the first four years (full-time equivalent research experience) of their research careers and not yet have been awarded a doctoral degree or be in a position to apply for one.
- Studies pursued: Applicants must hold a higher education degree that makes them eligible to enroll in a doctoral programme before starting at their host institutions.
The host university will verify, upon starting the admission process to the doctoral programme, that the studies taken up by the selected candidates make them eligible to enroll in an official doctoral programme in accordance with the regulations in force in Spain or Portugal. Should they be found not eligible after verification, the fellowship will be withdrawn.
