About this position
Postdoctoral position in Raman-based detection of micro- and nanoplastics is available at the University of Bern and Eawag in Switzerland. The two-year, full-time project investigates micro- and nanoplastic particles released from dialysis tubing and filters, initially in dialysate and later in blood, other biological matrices, and possibly kidney tissue.
The postdoctoral researcher will develop and validate an analytical workflow based on spontaneous Raman microspectroscopy. Tasks include sample preparation, filtration, particle deposition, automated particle detection, spectral identification, quantification, and rigorous quality assurance and quality control. Complementary methods such as stimulated Raman scattering and optical photothermal infrared spectroscopy may also be used. The work is hosted primarily in the Particle Laboratory at Eawag in Dübendorf, with collaboration involving the Department of Nephrology at Inselspital Bern and the University of Bern.
Applicants should have a PhD in analytical chemistry, physics, materials science, environmental sciences, biomedical engineering, or a related field. Raman microspectroscopy or related vibrational spectroscopy experience is essential. Experience with particle analysis in complex matrices, biological sample preparation, automated microscopy, or Python/R-based spectral data processing is advantageous. English communication skills are required, while German is desirable.
The position is supervised by PD Dr. med. Fabienne Aregger and Dr. Ralf Kaegi, with additional contact through Prof. Dr. med. H.P. Marti. Salary follows University of Bern and Swiss National Science Foundation regulations. Applications require a motivation letter, CV with publications, PhD certificate, and contact details for two to three academic references. Apply by 15 December 2026 or until filled.
