Project Description

The project focuses on Contractile Injection Systems (CIS) — natural bacterial nanomachines used to deliver molecular cargo. CIS are engineered for:

1. Biomedical applications: Targeting antibiotic-resistant pathogens (e.g., Staphylococcus aureus) with engineered payloads such as CRISPR-Cas, antimicrobial peptides, or enzymes.

2. Insect pest management: Delivery of neuropeptides or RNAi to pest species, reducing chemical pesticide use while sparing beneficial insects.

Key Research Activities

• Microbiome sequencing and metagenomic mining for novel CIS candidates

• Recombinant expression and purification of CIS proteins

• High-resolution cryo-EM and cryo-ET imaging of CIS

• Protein engineering and molecular modeling (AlphaFold2, Rosetta)

• Functional assays in bacterial and insect systems to assess targeting and delivery efficiency

• Data analysis, interpretation, and publication preparation

• Collaboration with Halberg Group (Copenhagen) and Collin Lab (Lund)

Work Duties and Responsibilities

• Conduct high-quality, independent postdoctoral research on CIS structure, function, and engineering

• Identify and characterize novel CIS candidates through bioinformatic and experimental approaches

• Clone, express, and purify CIS complexes

• Perform cryo-EM and cryo-ET imaging for structural analysis

• Engineer CIS variants for delivery of specific biomolecules

• Conduct in vitro and in vivo functional assays

• Collaborate with interdisciplinary teams, contributing to publications, conference presentations, and grant writing

• Participate in training, mentoring, and pedagogical activities within the research group

Qualifications

Required:

• PhD (or equivalent) in molecular biology, microbiology, biochemistry, structural biology, biotechnology, or related field

• Maximum 8 years post-PhD (per MSCA rules)

• At least one peer-reviewed publication

• Experience in molecular biology, including cloning and protein expression

• Experience in cryo-EM, cryo-ET, or structural biology techniques

• Proficiency in English (oral and written)

• Ability to work independently and in interdisciplinary teams

Meritorious:

• Protein design or engineering experience

• Familiarity with AlphaFold2, Rosetta, or multimeric protein prediction

• Experience with microbiome sequencing or metagenomic data analysis

• Experience with host-pathogen models, antimicrobial peptides, CRISPR, or RNAi

• Insect model experience and functional delivery assays

• Prior interdisciplinary or collaborative research

Employment Details

• Duration: 3 years (fixed-term, full-time)

• Location: Lund University, Faculty of Medicine, Department of Experimental Medical Sciences

• Working on-site in Lund, Sweden; travel to Copenhagen, Stockholm, and national imaging facilities (MAX IV, SciLifeLab, CFIM) expected

• Position follows Swedish employment regulations for postdoctoral researchers

• Competitive salary with government benefits, generous holidays, occupational pension, and flexible working conditions
