PhD Position in Environmental Analytical Chemistry

VEGAS is a research institution of the University of Stuttgart. We conduct innovative research on the fate and transport of contaminants in the subsurface, advanced environmental analytical chemistry, and the development of sustainable remediation technologies. Our experiment-based research integrates state-of-the-art analytical techniques, including high-resolution mass spectrometry, with investigations of groundwater flow, transport and reaction processes in porous media across multiple scales - from laboratory experiments and analytical method development to large-scale experimental facilities and field pilot sites.

We are looking for a highly motivated PhD candidate to join our DFG-funded research project “IRIS-PFAS: Investigations to Reveal Isotope Signatures of PFAS through Orbitrap-CSIA: From Method Development to Application”.

About the Project

Per- and polyfluorinated alkyl substances (PFAS) are among the most persistent and problematic environmental contaminants of our time. There is an urgent need for methods that not only detect concentrations but also provide information about origin, transport, and transformation processes. The analysis of stable isotopes offers great potential in this regard, but has hardly been exploited to date. The aim of this project is to develop and establish a new analytical methodology for the isotope-specific characterization of PFAS based on high-resolution mass spectrometry (Orbitrap MS).

The project is deliberately exploratory in nature and takes into account the early stage of development of Orbitrap-based isotope analysis. The project will deliver validated analytical protocols, fundamental insights into isotope behavior of PFAS, and a proof-of-concept for isotope-based PFAS source tracing. By overcoming key limitations of traditional IRMS, the proposed research establishes a new analytical framework for environmental forensics of persistent pollutants.  For more Information about this project, see our Project page
