Do you want to contribute to top quality medical research?

Our research efforts in the EL Andaloussi´s lab focus on one of the greatest challenges facing modern therapeutics; delivery of macromolecules to target cells in vivo. Despite the unprecedented knowledge of diseases and their mechanisms due to advances in biomedical sciences; many promising therapeutic approaches are still clinically unavailable. This is simply because there is no efficient means of delivering these therapeutics to the right organ with the right dose. Our research performance involves developing novel and innovative drug delivery technologies that can carry proteins, RNAs or gene therapies to the target tissues safely and efficiently. In this connection, we engineer exosomes with enhanced delivery and targeting capacities and screen our wide array of exosome designs in disease-relevant cellular and animal models. To benchmark the efficacy of engineered exosomes, we also exploit established lipid nanoparticles, similar to those used in Covid-19 vaccines, for comparison. We also screen novel LNPs for improved RNA delivery capacity. Another research activity of the lab is to exploit novel small molecules (SMCs) that can robustly enhance endosomal escape of protein- and nucleic acid therapeutics. Thus, our research platform offers a unique opportunity for discovering, manufacturing and delivery of advanced therapeutics.  

Your mission

As a Postdoctoral Research fellow, you will work on the development of bioengineered extracellular vesicles (EVs) and testing novel LNPs to enhance delivery of oligonucleotides and therapeutic mRNAs.

Most of the research will be conducted utilizing cell lines and animal models. The first part of the work will involve developing stable cell lines for production of EVs engineered to harbor reporter proteins. Uptake of EVs derived from different cells will then be assessed in different recipient cells. The best EV source will then be engineered to contain mRNA or short RNAs and tested for functional delivery in relevant reporter cell lines (the reporter cell lines are already established in the lab). Successful candidate constructs will later be developed to target disease relevant targets firstly in vitro and later in vivo. In parallel, LNPs will be screened for delivery of splice switching oligonucleotides and mRNA therapeutics. The work will be highly innovative and require extensive knowledge regarding molecular biology techniques, cell culture and the process of making stable cells via lentivirus transduction or transposon transfections, as well as formulation work and downstream characterization of nanoparticles.

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.

The applicant should have a solid background in basic biology and drug delivery. The position requires practical lab experience in the following areas; foremost experience with molecular engineering and isolation/characterization of EVs. Secondly, previous experience from formulation and application of LNPs and other nanoparticles for RNA delivery is critical. In addition, experience with flow cytometric analysis of protein expression and experience with PCR related techniques. The ideal candidate would furthermore have experience within the EV or virus field. The applicant must hold a FELASA level animal license and have extensive experience from experimental work in rodents.

In addition, excellent proficiency in both spoken and written English is important. We are looking for an energetic and passionate person who fits in, and actively contributes to our team.
