Reference number 3704 - Postdoc for the investigation of mixtures using organs-on-a-chip (f/m/x) in the Pesticide Safety Division of the Federal Institute for Risk Assessment (BfRshort forGerman Federal Institute for Risk Assessment)
BfRshort forGerman Federal Institute for Risk Assessment independently prepares expert opinions and statements on issues of food, feed and chemical safety and consumer health protection in Germany on the basis of internationally recognised scientific evaluation criteria. It advises the Federal Government and other institutions and interest groups in these areas. BfRshort forGerman Federal Institute for Risk Assessment thus makes an important contribution to the protection of human health.
The position is part-time, with 65% of the regular weekly working hours (currently 25.35 hours) and should be used for a doctorate. Participation in the accompanying doctoral programme is compulsory. This serves to impart both scientific and methodological knowledge and offers the opportunity to regularly present doctoral projects in internal events and benefit from scientific exchange.

The fixed term is based on the German Academic Fixed-Term Contract Act.
Tasks
The assessment of mixtures and their toxicity remains a regulatory and scientific challenge. Microphysiological systems (MPS) are ideal to assess mixture toxicity across uptake barriers and provide a realistic setting to investigate multi-organ interaction. Therefore, they shall be established and applied to investigate realistic systemic co-exposureExposureTo glossary to food-borne toxicants and provide the experimental setting to unravel biochemical pathways of toxicity and interaction of the most relevant substances and mixtures in our diet. As a long-term goal, this work shall contribute to understanding low dose mixture effects and derive regulatory strategies to address them across multiple regulatory silos. The activities include in detail:
- Experimental work in vitro to investigate mixtures with human cell lines and organoids in microphysiological systems (MPS)
- Establish organoid and 3D cell culture in our laboratories
- Create a strategy to replace and minimise the use of fetal bovine serum in MPS and in vitro testing
- Development and application of chemical analytical methods
- Participation in the preparation of scientific publications and presentation of results at meetings and in expert panels
- Support in the supervision of practical laboratory work of PhD and Master’s students
Your profile
- University degree (Master's degree, diploma or equivalent) in biology, biochemistry, chemistry, food chemistry, toxicology, pharmacy or (veterinary) medicine or a comparable discipline
- Advanced knowledge in toxicology (e.g. through advanced training courses, relevant study programme or work experience)
- Proficiency in written and spoken English
- Flexibility, team spirit and the ability to work under pressure
Desired
- PhD in one of the above or a comparable discipline
- Experience in statistical analysis and programming languages, especially R
- Practical experience in cell culture including 3D cell culture or organoid systems
- Practical experience in chemical analysis
- Practical experience in organs-on-a-chip and MPS
- German language skills
What we can offer you
- Flexible working hours without core working hours
- 30 days’ annual leave (5-day week) plus 24 and 31 December as non-working days
