In the department Safety in the Food Chain of the BfR is in the unit “Plants and Mycotoxins” from immediately temporary to fill the following position: Doctoral candidate chemical analysis of contaminants in food using high-resolution mass spectrometry (f/m/x) Reference number: 3162/2022 | Salary group 13 TVöD | Place of employment: Berlin | Application deadline 29 January 2023, The position is part-time, with 65 % of the regular weekly working hours (currently 25.35 hours).

This position is being advertised within the framework of the EU project “Holistic approach for tackling food systems risks in a changing global environment” (HOLiFOOD). The aim of the project is to develop a holistic approach to risk assessment and management. The doctoral thesis focuses on methods for identifying new chemical risks through suspect/non-target screening, anomaly screening and marker identification using high-resolution mass spectrometry.

In cooperation with project partners, deep learning and AI methods are also applied and data evaluation approaches and data management systems are developed. Furthermore, related aspects from the EU project PARC (Partnership for the Assessment of Risk from Chemicals) are dealt with. The position 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.


In the “Plant and Mycotoxins” unit, chemical-analytical methods for determining these toxins are developed and validated. These methods are used to examine food, feed and biological matrices as part of the National Reference Laboratory and research projects.

The individual tasks include:

  • Advancement of analytical approaches for suspect target/non-target screening of food, feed and biological samples using liquid chromatography coupled with high-resolution mass spectrometry (LC-HRMS) to identify contaminants (especially mycotoxins and plant toxins) 
  • Application and advancement of methods for data evaluation
  • Analysis of samples with the developed approaches, documentation and evaluation of experimental data and their assessment
  • In vitro digestion of mycotoxins
  • Cooperation with the European project partners
  • Presentation of results at symposia and preparation of scientific publications


  •  University degree (master’s, diploma or equivalent university degree) in chemistry, food chemistry or a similar subject
  • Good knowledge of instrumental analytics, chromatographic and mass spectrometric methods notably required
  • Practical experience in the analysis of food, feed, plant material or biological matrices is an advantage
  • Knowledge of computer science, bioinformatics or similar, programming skills, experience with AI/machine learning are desirable
  • Knowledge of the evaluation of complex data using statistical or chemometric methods is an advantage
  • Experience in presenting and publishing scientific results is desired
  • Good knowledge of spoken and written German and English is required
  • Very good computer skills and a structured, conscientious way of working, organisational skills, flexibility, teamwork and resilience, as well as willingness to travel on business, are required
