PhD student (m/f/d)

Leibniz Institute for Food Systems Biology (LSB), Freising

The Leibniz Institute for Food Systems Biology at the Technical University of Munich (Leibniz- LSB@TUM), a legal foundation under civil law in Freising, is a research institution of the Leibniz Association that combines methods of biomolecular basic research with analysis methods of bioinformatics and analytical high-performance technologies to investigate the complex interplay between the human organism and food ingredients.

The research group Biosystems Chemistry and Human Metabolism at Leibniz-LSB@TUM is currently looking for a scientist to start on 1.6.2022 as

PhD student (m/f/d)

to collaborate in a project “analytical metabolomics studies of dietary bioactive diterpene glycosides”, which is supervised by Dr. Roman Lang. The position is to be filled on a part-time (65%, TV-L 13) basis for a period of 1 year with the option to extend for further 3 years.

Your area of responsibility includes
  • Development of work flows to isolate and purify bioactive diterpene glycosides from plant material
  • Establishing microsomes-based in-vitro metabolism to study formation of metabolites, and upscaling for preparative isolation
  • Structure-elucidation of generated metabolites with NMR and MS techniques
  • Development of targeted MS and MS/MS based quantitation methods for analysis of such metabolites in biosamples (urine, blood, saliva)
  • Collaboration in the LC-MS-Team
  • Care of the preparative and analytical LC-systems


The ideal applicant has

  • an MSc degree in food science/food chemistry
  • previous knowledge in compound isolation and purification with preparative liquid chromatography
  • previous knowledge in quantitative analysis, particularly U(H)PLC-MS/MS and stable-isotope dilution analysis
  • interest in metabolomics-oriented aspects in the area of food chemistry

Work environment:

Together with internationally recognized experts, you conduct research aimed at improving foodstuffs and promoting healthy human nutrition.

In addition to a varied workplace where your performance counts, we offer

  • a performance-related salary in accordance with TV-L, in-line with your personal qualifications and the personal prerequisites
  • an interesting and varied task area in the field of university research
  • a motivated team that is looking forward to welcoming you
  • flexible working times and therefore good compatibility of work and family
  • company pension scheme
  • special annual payment

In the case of essentially reciprocal suitability, severely-disabled applicants as defined SGB IX will be preferred.

Please address any questions on current topics to Mr. Dr. Roman Lang (r.lang.leibniz-lsb@tum.de) and send your application with the usual documents/containing your comprehensive CV and transcripts as well as names of three potential references electronically as a merged PDF file to the following address, citing the reference number 2022-06-S1-RL to Kama Dukat-Bauer (Administrative Staff) at recruiting.leibniz-lsb@tum.de.
