Contract:

Temporary, Full-time. Offer Starting Date: 16 Mar 2026. Not funded by an EU programme. Reference Number: BAP‑2026‑49. Not a research infrastructure staff position.

You will take ownership of a research line and lead its scientific development. You will design and coordinate in‑vitro and in‑vivo studies to investigate host‑pathogen interactions, develop advanced methodologies for antibody characterisation (ADE, ADCC), implement yeast‑surface display for mapping antibody–antigen interactions, and establish systems for recombinant antigen expression. A key responsibility will be contributing to the development and characterisation of transgenic and knockout mouse and hamster models.

You will mentor junior researchers, supervise Master’s and PhD students, guide technicians, ensure rigorous data analysis, timely reporting, and achievement of project milestones. Active involvement in grant writing, scientific presentations, and collaborative initiatives will be expected.

You hold a PhD in virology, molecular biology, or a related field. You combine strong analytical skills with the ability to work independently, lead collaborative efforts, and are team‑oriented, proactive, solution‑oriented, and comfortable taking ownership of complex projects. Excellent English communication skills and a proven publication record are essential.

We seek strong molecular biology expertise as the foundation for this role, complemented by virology and immunology skills. Relevant experience includes:

• Molecular cloning and plasmid design, including infectious clones and complex constructs
• Use of lentiviral systems for gene delivery and functional studies
• Application of CRISPR/Cas technologies for genome editing and functional validation
• Recombinant protein and antigen expression for vaccine and diagnostic development
• Development and optimisation of advanced immunological assays (ADE/ADCC) and yeast‑surface display for antibody–antigen interaction studies
• Cell‑based virus assays (multi‑colour flow cytometry, primary cell culture – an advantage)
• Experience in animal experimentation (FELASA B/C or equivalent) and development of transgenic and knockout mouse and hamster models – an advantage
• Familiarity with data analysis, bioinformatics and modelling for transcriptomics and immunoprofiling – an advantage
• Knowledge of BSL3 laboratory procedures – an advantage

You will work within one of Europe’s most innovative universities, KU Leuven, and the internationally recognised Rega Institute. You will have access to cutting‑edge technologies, a broad collaborative network, and a stimulating research environment in Leuven, a historic city at the heart of Europe.

Starting date: as soon as possible.

The following information will be considered:

• Motivation letter summarising your research experience and indicating what attracts you to this position and how you match the desired experience
• CV
• Diploma and transcripts of records (BSc, MSc, PhD)
• Contact details of at least two reference persons
• Other information for consideration (e.g., a list of publications)
