The following position is available immediately in the Pesticide Safety Division of the Federal Institute for Risk Assessment (BfR):

BfR independently prepares expert opinions and statements on issues of food, feed, and chemical safety and consumer health protection in Germany based on internationally recognized scientific evaluation criteria. It advises the Federal Government and other institutions and interest groups in these areas. BfR thus contributes significantly to the protection of human health.

The position is part-time, with 65% of the regular weekly working hours (currently 25.35 hours) and is intended for pursuing a doctorate. Participation in the accompanying doctoral program is mandatory. This program imparts scientific and methodological knowledge and provides opportunities to present doctoral projects in internal events and benefit from scientific exchange.

Further information about the remit of the Department can be found here on our homepage. The fixed term complies with the German Academic Fixed-Term Contract Act.

The assessment of mixtures and their toxicity remains a regulatory and scientific challenge. The planned PhD project will investigate the interaction of food-borne toxicants with realistic co-exposure using New Approach Methods (NAMs). The focus will be on systematically investigating mechanisms of mixture toxicity in the low-dose range. This position supports research into regulatory concepts for the risk assessment of mixtures, aiming to understand low-dose mixture effects and develop regulatory strategies across multiple regulatory silos. Specific activities include:

• Experimental work in vitro with human cell lines and organoids in microphysiological systems (MPS)
• Systematic testing of whole mixtures and single substances, and calculation of mixture toxicity
• Development and application of chemical analytical methods
• Application of physiology-based kinetic (PBK) modelling for extrapolation of in vitro to in vivo concentrations (IVIVE)
• Participation in scientific publications and presentation of results at meetings and expert panels
• Supervision support for practical laboratory work of Master’s students

• University degree (Master's, diploma, or equivalent) in biology, biochemistry, chemistry, food chemistry, toxicology, pharmacy, (veterinary) medicine, or a comparable field
• Basic knowledge in toxicology (through training, relevant studies, or work experience)
• Proficiency in written and spoken English
• Flexibility, team spirit, and ability to work under pressure
• Practical experience in cell culture
• Practical experience in chemical analysis
• Experience with statistical analysis and programming languages, especially R

• Trust-based working hours
• 30 days’ annual leave plus non-working days on 24 and 31 December
• Subsidy for the Deutschlandticket Job
• Hybrid working options
• Excellent public transport connections
• Opportunities for professional and personal development
