High-throughput SAXS for Lipid Nanoparticle Structure and Function

Are you interested in developing next-generation scattering methods for one of the most important challenges in modern therapeutics

We are seeking a highly motivated postdoctoral researcher to join the CoSAXS beamline at MAX IV and the Edler Group at Lund University to develop high-throughput SAXS/WAXS approaches for understanding the structure and function of solid lipid nanoparticles.

This 36 month position offers the opportunity to work at one of the worlds most advanced synchrotron facilities within an international and interdisciplinary research environment spanning soft matter physics structural biology nanomedicine and advanced data analysis. The fellowship is funded through the prestigious AMBER Marie Skłodowska-Curie COFUND programme.

The Research Environment

The position is hosted jointly by the CoSAXS beamline and the Edler goup at Lund University.

CoSAXS ( is a state-of-the-art SAXS/WAXS beamline operating on the 3 GeV storage ring at MAX IV one of the worlds leading fourth-generation synchrotron sources. The beamline supports research in soft matter biological materials and nanostructured systems through advanced instrumentation and flexible sample environments.

The Edler Group ( focuses on understanding how hierarchical functional materials form and how this understanding can be used to design new materials with tailored properties. Research in the group centres on self-assembly processes involving nanoparticles surfactants polymers lipid systems and other soft matter components with particular emphasis on how nanoscale interactions govern structure and function across multiple length scales. The group combines advanced scattering and diffraction methods with a broad suite of complementary characterisation techniques such as TEM SEM AFM NMR light scattering XRD and neutron scattering approaches.

The project also involves collaboration with researchers at ESS and ISIS Neutron and Muon Source as part of the ESS First Science initiative The Lifecycle of a Lipid Nanoparticle.

The Project: High-throughput SAXS for Visualising Solid Lipid Nanoparticles

Lipid nanoparticles are rapidly transforming the field of drug delivery including RNA therapeutics and precision medicine. Despite their importance many fundamental questions remain about how nanoparticle structure governs encapsulation stability transport and biological performance. This project aims to establish direct links between nanoscale structure and function in lipid nanoparticles using advanced synchrotron SAXS/WAXS methods at MAX IV.

The postdoctoral researcher will play a central role in developing new experimental and analytical capabilities for high-throughput lipid nanoparticle characterisation at CoSAXS. The work combines synchrotron experiments advanced scattering analysis and collaborative method development.

The successful candidate will:

• design plan and perform SAXS/WAXS experiments on solid lipid nanoparticles and related soft matter systems
• develop high-throughput workflows for nanoparticle characterisation at CoSAXS
• investigate nanoparticle formation pathways internal organisation and structural evolution
• analyse scattering data using advanced computational approaches including atomistic and coarse-grained modelling
• contribute to the development of data analysis tools for complex nanoparticle systems
• participate in neutron and synchrotron experiments at international large-scale facilities
• support relevant user experiments and contribute to the broader scientific activities of the beamline
• train and support users in scattering workflows and analysis methods
• contribute to supervision of student projects and collaborative research activities
• disseminate research through publications conference presentations workshops and international collaborations

The position offers a unique opportunity to contribute both to frontier research in nanostructured therapeutics and to the development of next-generation experimental methods for the wider scientific community.

We are looking for an ambitious and collaborative researcher with strong experimental and analytical skills. Applicants should have:

• PhD in a relevant science area biophysics lipid/amphiphile based physical chemistry or equivalent
• Proven expertise in SAXS/WAXS and data interpretation
• Proven experience in the use of synchrotron SAXS/WAXS for lipid or surfactant self-assembled structure determination
• Documented expertise in data reduction and analysis using scripting (ideally python-based)
• Experience carrying out SAXS/WAXS experiments at large scale facilities ideally from self-authored proposals
• Working experience with soft matter and/or protein systems including sample preparation for SAXS measurements
• Ability to work independently and take initiatives
• Strong social and communication skills
• Good command of written and spoken English

Experience with lipid systems surfactants nanoparticle self-assembly atomistic modelling or beamline environments will be considered an advantage.
