The research group

The laboratory for protein misfolding and assembly at BioNut ( currently consists of one professor, two associate professors, two senior research specialists, three post-docs and three PhD students. We have discovered how a molecular chaperone domain (BRICHOS) prevents cell toxic effects of protein misfolding and shown in cell and animal models that recombinant BRICHOS passes the blood brain barrier (BBB) and has potential to treat neurodegenerative diseases, including Alzheimer´s disease (AD).

Your mission

Protein misfolding and aggregation is a cause of disease, and self-assembly into amyloid fibrils is linked to different devastating human diseases including AD, which poses an urgent social-economical challenge for the society. Major research efforts have been undertaken to understand the disease pathophysiology, and to develop disease-modifying therapies, but novel approaches are urgently needed.

BRICHOS is present in proteins that harbour a region with high propensity for amyloid formation, and the role of this chaperone domain is to protect these amyloidogenic regions from harming cells. Notably, mutations in the BRICHOS domain can lead to lethal disease. Recombinant BRICHOS domains also recognise “non-client” amyloid peptides linked to different human diseases, for example AD. Further, the BRICHOS domain passes the BBB which makes it a realistic and attractive agent to harness for various applications in neurodegenerative disorders.

The successful postdoc will study recombinant BRICHOS in cell and animal models and explore if BRICHOS can carry drugs over the BBB.

Your profile

To be eligible for employment as a postdoctor a doctoral degree or a foreign degree deemed to be equivalent to a doctoral degree is required. This eligibility requirement must be fulfilled at the latest at the time of the employment decision. It is considered as an advantage if you have completed your doctoral degree within the last three years, if there are special reasons, your degree may have been completed earlier.


  • PhD in medicine, biochemistry, biomedicine, cell or molecular biology, or another relevant    field. 
  • Documented experience of protein biochemistry, molecular chaperones, cell and animal experiments, immunochemistry, and similar techniques.
  • Excellent communications skills
    Fluency in spoken and written English 

Additional merits

Since the position involves close interaction with several researchers, emphasis is also placed on personal skills. The successful applicant should have the ability to work independently and as part of a team, and be open for collaborations. Good data management and documentation skills are also required.
