Postdoc in Viscoelasticity for Highly Viscous Fibres in Conventional Melt Processing Equipment
Chalmers University of Technology in Gothenburg, Sweden, invites applications for a postdoctoral position in viscoelasticity for highly viscous fibres in conventional melt processing equipment. The research is situated within the Division for Computational Mechanics and Materials Engineering, part of the Department of Mechanical Engineering. The division is renowned for its focus on sustainable circular materials, aiming to replace oil-based plastics and reduce environmental impact.
The project addresses the urgent need for alternatives to fossil-based plastics, leveraging advances in the thermoplasticity of biosourced fibres such as lignocellulosic fibres. The research aims to develop new methods to study and understand the viscoelasticity of highly viscous fibre-based materials, improving their processability in conventional melt processing equipment. This will enable the design of sustainable fibre-based materials as alternatives to traditional thermoplastics. Reactive extrusion strategies will be explored to overcome challenges like water sensitivity, and the project will evaluate end-of-life scenarios including recyclability, re-pulpability, and biodegradation in composting environments.
Material characterisation is a key aspect, involving structural, physical, and chemical analysis to deepen understanding of structure-processing-properties relationships. The postdoc will participate in several projects, collaborate with Swedish partners in FibRe, and work with international collaborators such as the Polytechnic Institute of Torino, University of Pisa, and Tetra Pak. The role also includes proposing new research projects to Swedish and European funding agencies.
Applicants must have a doctoral degree or equivalent, strong English communication skills, and experience in polymer melt processing and rheology. Familiarity with laboratory equipment (rheometers, tensile testers) and advanced characterisation techniques (AFM, SEM, TEM, FTIR, XRD, TGA, DSC, fluorescence spectroscopy) is required. The ability to collaborate in interdisciplinary teams, take initiative, work independently, and contribute to teaching is essential. A recent doctoral degree in chemical engineering, materials or polymers engineering, or related fields is advantageous, especially with experience in biomaterials modification, melt processing, and rheology.
The position is a full-time, temporary employment for two years, with the possibility of a one-year extension. Physical presence is required throughout the employment, and a valid residence permit must be presented by the start date. Chalmers offers a dynamic work environment, employee benefits, and support for settling in Sweden, including Swedish language courses. The university is committed to gender balance, equality, and inclusion.
To apply, submit your application via the online form by 8th May 2026. Attach your CV, publication list, teaching experience, and personal letter as PDF files. Incomplete or emailed applications will not be considered. References will be requested after the interview. For questions, contact Associate Professor Giada Lo Re at [email protected].
This postdoctoral opportunity is ideal for candidates seeking to advance their research careers in academia, industry, or the public sector, contributing to the development of sustainable materials and innovative processing techniques.
