The physical cosmology group at ICCUB ( is looking for a talented and highly motivated student interested in doing a PhD in observational cosmology at ICCUB (, University of Barcelona ( A completed university master degree with documented knowledge in project-relevant areas is required. Programming knowledge and experience working with cosmological datasets will be highly considered. The position is for 3 years (subject to satisfactory progress towards a PhD), and includes the contribution to the social security and national healthcare system to be paid by the employer (with employee contribution through standard taxes).

The student will join the DESI collaboration and will have the opportunity to collaborate with other members of the ICCUB. The Dark Energy Spectroscopic Instrument, DESI (, is the cornerstone for the wider and most ambitious spectroscopic galaxy survey ever undertaken, with first light in 2019. It will measure 4 million Luminous Red Galaxies below redshift 1; 17 million of Emission Luminous Galaxies below redshift 1.6 and 2.4 million quasars between redshifts 0.9 and 3.5 among other programs. The large volume covered by DESI will allow sub-percent measurements on cosmological parameters, such the Baryon Acoustic Oscillation angular diameter distance and the Hubble parameter. Reaching such a level of precision is key to discriminate among different models of Dark Energy, to set constrains on the total amount of neutrino masses and to test GR as a theory of gravity at the largest regime ever explored, the size of the Universe.

Project: The student will work on developing methods to maximize the scientific return of DESI data by developing robust analyses techniques, by controlling and minimizing the impact of observational systematics, a necessary preliminary step for subsequently explore novel approaches and apply them to analyze the data provided by DESI in an optimal way. These techniques will be eventually applied by the student to the first science data produced by the DESI during its first years of observation. The bulk of the funding is provided by the prestigious “La Caixa” fellowship awarded to Dr. Héctor Gil-Marín who will move to ICCUB in the fall. The project will be supervised by Prof. Licia Verde (,, and Dr. Héctor Gil-Marín (, Informal scientific inquiries about the project should be addressed to them.

The ICCUB is an interdisciplinary center devoted to fundamental research in cosmology, astrophysics and particle physics. It is one of the few Spanish research institutes awarded with the Maria de Maeztu distinction for excellence in research and provides a dynamic and stimulating environment for young researchers.

Application: Candidates must submit a one-page research interests statement, a curriculum vitae and arrange for two reference letters to be uploaded [from this page] by July 15th 2018 for a full consideration. Later applications may be considered until the position is filled.
