This post compiles a curated list of top Spanish research institutions and portals offering PhD and postdoctoral opportunities in fields such as materials science, nanotechnology, biomedical engineering, and related interdisciplinary areas. The highlighted institutions include Ikerbasque (Basque Foundation for Science), CSIC (Consejo Superior de Investigaciones Científicas), Universidad Complutense de Madrid, Universitat Autònoma de Barcelona, and CIC biomaGUNE, among others. These organizations regularly announce fully funded PhD fellowships and postdoctoral positions in cutting-edge research areas, including immunotherapy, biodegradable nanoparticles for theranostic applications, and computational biology.

For example, CIC biomaGUNE currently offers a PhD fellowship in the Molecular and Functional Biomarkers Laboratory, focusing on the development of biodegradable nanomaterials for oncology theranostics, and a postdoctoral position in the Biomolecular Nanotechnology Lab, working on computational and microfluidic immunopeptide discovery for cancer immunotherapy. Supervisors for these positions include Dr. Susana Carregal-Romero, Prof. Fernando López-Gallego, and Dr. Aitziber L. Cortajarena, all based at CIC biomaGUNE in Spain.

Applicants for PhD positions should have a relevant master's degree in materials science, chemistry, biology, biomedical engineering, or a related field, while postdoctoral candidates must hold a PhD in a related discipline. Experience in nanomaterials synthesis, characterization, or computational biology is advantageous. Proficiency in English and a strong motivation for interdisciplinary research are required. Funding is typically fully covered, with stipends and research expenses provided. Some programs, such as MSCA COFUND, offer additional training and international collaboration opportunities.

To apply, candidates should visit the respective institutional job portals, review current openings, and submit their applications through the official systems.
