Postdoc position in thermodynamic modelling of PFAS properties DTU Chemistry

DTU Chemistry is seeking a talented researcher to develop advanced thermodynamic models for predicting phase equilibria and thermophysical properties of PFAS. This position offers an excellent opportunity for an early-career scientist to build a strong foundation and conduct cutting-edge research at the forefront of the field.

PFAS are highly persistent environmental contaminants that pose serious ecological and health risks. Their low concentration and complex behavior make experimental analyses challenging. Developing reliable predictive models is essential to reduce the reliance on experiments and enhance the accuracy of property and phase equilibrium this project we aim to advance the COSMO-based thermodynamic models to accurately predict the phase equilibria and key physicochemical properties of PFAS thereby supporting environmental risk assessments and optimization of removal technologies.

Responsibilities and qualifications
The postdoctoral researcher will work on the thermodynamic modeling of PFAS-containing mixtures focusing on improving predictive models such as COSMO-RS for phase equilibria and relevant physicochemical properties.

The ideal candidate should have:

• A strong background in thermodynamics and phase behavior of complex mixtures
• Excellent programming skills (e.g. Python C Fortran or similar)
• Experience with COSMO-based methods including parameterization model development and computational algorithms
• A solid understanding of theoretical chemistry and solvation models such as COSMO
• The ability to work independently as well as collaboratively within a multidisciplinary research environment

As a formal qualification you must hold a PhD degree (or equivalent).

We offer
DTU is a leading technical university globally recognized for the excellence of its research education innovation and scientific advice.
