Research Technician position within Biophysics of Lipoproteins and Lipid Nanoparticles
Job Summary
Research Technician position opportunity
We seek a motivated Chemist, Biochemist, BioPhysicist, Pharmacist to occupy a technical position joining the Biocolloids and Neutron Scattering Laboratory, led by Prof. Marité Cárdenas, to work on the research project "Physicochemical determinants of lipid nanoparticle and lipoprotein function" (Grant PID2025-170281NB-I00 funded by MICIU/AEI /10.13039/501100011033 and by ERDF, EU)
Job Description & Benefits
The project aims to elucidate the nano-physicochemical determinants governing the structure, heterogeneity and protein-corona formation of both natural lipoproteins (HDL) and synthetic lipid nanoparticles (LNPs), and to relate these properties to their biological function. By integrating bulk and single-particle biophysical approaches, the research seeks to uncover the molecular basis of HDL dysfunction and identify the factors determining the efficiency of LNP cellular delivery and endosomal escape.
The position involves tasks covering the purification of lipoproteins and preparation of lipid nanoparticles, their characterization using OMICS approaches, implementing protocols to perform single particle profiling to analyse differences in lipoprotein and lipid nanoparticles at the single particle level and also to perform functional cell-based tests such as cholesterol efflux capacity and anti-inflammatory properties. Among the tasks we include quantitative data analysis.
The successful candidate will be appointed through a one-year ResearchTechnical contract with possibility for prolongation for the duration of the project. The candidate will join Instituto Biofisika (IBF).
The project includes close collaboration with leading research groups in the Basque Country, Spain, and abroad, as well as experimental use of major international large-scale research infrastructures, including the Institut Laue-Langevin (France), ESRF (France), EMBL (Germany), the European Spallation Source (Sweden), and the ISIS Neutron and Muon Source (United Kingdom).
About Instituto Biofisika
Instituto Biofisika (IBF) is a joint research center of the University of the Basque Country (UPV/EHU) and the Spanish National Research Council (CSIC). Together with Fundación BiofÃsica Bizkaia, a Basque Excellence Research Centre (BERC), IBF provides an internationally recognized environment for interdisciplinary research in biophysics, structural biology, and advanced imaging.
Located on the UPV/EHU campus near Bilbao, the institute hosts internationally competitive research groups and offers access to state-of-the-art scientific infrastructure.
Research Environment
The successful candidate will join the Biocolloids and Neutron Scattering Laboratory, an internationally active research group specialized in the physicochemical characterization of biological colloids and membrane systems. The candidate will have opportunities to perform experiments at international neutron and synchrotron facilities and to present research at international conferences. The candidate will have the possibility to start studies as a PhD student, if so it is desired.
