The CaixaResearch Institute is a newly established immunology research centre with the mission of becoming a integral leader in immunological research. It focuses on studying immune system processes and their interaction with the most prevalent diseases, including neurological, oncological, and infectious conditions, as well as on analysing the influence of environmental factors. The institute is devoted to understanding the role of the immune system in health and disease, analysing the environmental factors that influence these processes, and developing advanced technologies to observe and decode them in greater detail.

The institute is part of the rich ecosystem of biomedical research centres supported by the “la Caixa” Foundation, which includes ISGlobal, the Barcelona Beta Brain Research Centre (BBRC), VHIO, IRSICaixa, and the Sant Joan de Déu Foundation—all based in Barcelona—as well as The Gulbenkian Institute for Molecular Medicine (GIMM) in Lisbon.

CaixaResearch Institute invites applications from outstanding predoctoral researchers interested in applying for a Formación de Profesorado Universitario (FPU) 2026 granted by Agencia Estatal de Investigación in the field of biomedicine.

FPU aims to support early-stage researchers in developing their scientific careers and completing a PhD. FPU fellows will carry out an original doctoral research project for 4 years, gaining advanced knowledge, skills and experience to contribute to scientific progress.

Candidates are encouraged to review the list of CaixaResearch Institute labs currently accepting FPU fellows (see below) to identify research areas that align with their interests and find an appropriate CaixaResearch Institute supervisor.

Host laboratory and field of expertise

Mittelbrunn Lab

We are looking for a motivated PhD candidate to join our lab under the FPU program, working on the cellular and molecular mechanisms underlying immune aging (immunosenescence).

The project combines animal models with longitudinal human samples to study how aging reshapes innate and adaptive immune cell populations and function, using state-of-the-art approaches including spectral flow cytometry, scRNA seq and functional assays. A key goal is to understand how age-related immune remodelling contributes to chronic low-grade inflammation ("inflammaging"), and susceptibility to disease.

· Keywords: Immune aging, immunosenescence, inflammaging,

· Preferred expertise: Background in immunology, aging biology, or cellular biology, experience with spectral flow cytometry or cell culture is a strong plus, Comfortable working with animal models, enthusiastic, with strong teamwork skills

If you are interested in applying for a FPU Fellowship with this lab as host please apply including CV, academic record and letter of interest.

* For qualifications obtained outside Spain you must attach the declaration of equivalence of the grade point average (MICIU electronic office) of both bachelor and master, if applicable.
