Postdoctoral Fellow in Enzymatic Polymerization Technology
Royal Institute of Technology School of Chemistry, Biotechnology and Health

KTH, School of Chemistry, Biotechnology and Health


KTH is one of Europe's leading technical universities and an important arena for knowledge development. As Sweden's largest university for technical research and education, we gather students, researchers and faculty from all over the world. Our research and education encompasses both natural science and all branches of technology as well as architecture, industrial economics, social planning, history and philosophy.


Syrén's research group ( ) recruits a postdoctoral researcher within "enzymatic polymerization technology with a focus on recycling of synthetic materials" in close collaboration with Professor Hakkarainen. The successful candidate will develop enzyme-based technologies for polymer recovery within this interdisciplinary project, together with leading research groups at KTH in synthetic biology (Assoc. Prof. Per-Olof Syrén) and polymer technology (Prof. Minna Hakkarainen). Close collaboration with the Department of Fiber and Polymer Technology and Science for Life Laboratory will enable the project's interdisciplinary approach.


The main objective of this project is to develop biotechnological methods for enzyme-assisted recovery of synthetic polymers by mild hydrolysis. The research area of the postdoctoral fellow is focused on biocatalysis and the use of hydrolytic enzymes, such as cutinases, for depolymerization of synthetic materials into monomers. Chemo-enzymatic recovery methods and the development of green enzyme-based processes for polymerizing generated monomers back to material are also included in the work tasks. The successful candidate will perform work within the borderland between biotechnology and polymer technology, which includes:

  • Evaluation of catalytic potential of biocatalysts in degradation of synthetic polymers to monomers.
  • Application of tailor-made enzymes in material chemical applications.
  • Analysis of polymers and released monomers / oligomers with experimental tools.
  • Optimization of reaction conditions for mild enzymatic depolymerization / polymerization.
  • Actively contribute to the research group's activities, eg through supervision of candidate / master students in the laboratory.

The start date is open for discussion, but we would like the service to be appointed as soon as possible. This service is a full-time service of one year with the possibility of extension for another year.


The successful candidate should be able to demonstrate good knowledge in formulating writing in advanced publications and be able to demonstrate good knowledge of English and oral presentation techniques. The ideal candidate possesses the following qualifications:

  • Scientific proficiency with relevant doctoral degree, ie within polymer chemistry and / or biocatalysis and related fields.
  • Experience of suitable characterization techniques of polymeric materials and its building blocks, such as SEM, FTIR, GC-MS, NMR, MALDI-TOF.
  • Experience with enzyme catalysis applied to polymers.
  • Experience of molecular biology and / or polymer chemical laboratory work.

In addition to basic chemistry, polymer and biotechnology knowledge, experience of interdisciplinary work and competence in protein design, protein engineering, biocatalysis and bioinformatics is counted as a credit. In-depth knowledge of molecular biology, analytical chemistry, characterization of materials and mass spectrometry and organic chemistry is also an advantage. For the employment, a doctorate must be obtained within three years before the application deadline.

As a person you should possess personal and professional maturity, be self-sustaining and responsible. We assume that you should have good collaboration skills and be communicative. You should also have a good analytical and problem solving ability. We will attach great importance to personal fitness.
