Postdoc – Mass Spectrometry and Molecular Biology of Epigenetic DNA/RNA Modifications (#CNPD12)

The Institute of Molecular Biology gGmbH (IMB) is a Centre of Excellence for Life Sciences, funded by the Boehringer Ingelheim Foundation. It is located within the campus of the Johannes Gutenberg-University, Mainz, Germany.

Job description:

The ERC-funded laboratory of Christof Niehrs studies regulatory DNA and RNA modifications, which play important roles in development & disease. We utilize highly sensitive mass spectrometry (Triple Quadrupole Mass Spec) and stable isotope metabolic labelling to profile epigenetic and epitranscriptomic changes, including 5mC, 5hmC, 5fC, 5caC, m6A, and others. The successful candidate will study nucleic acid modifying enzymes to unravel how chemical modifications in DNA, RNA and R-loops regulate pluripotency and differentiation of mammalian embryonic stem cells and embryos. See also You will use mass spectrometry, genome-edited CRISPR/Cas9 stem cell mutants, as well as various NGS protocols to carry out a multi- dimensional analysis to address: Which modifications can be identified and how do they change with different cellular states? Where in the genome and in which RNAs do the modifications occur? What are molecular determinants involved in targeting of modifications to specific sites? The project will involve strong interaction with computational biologists.


  • PhD & publications in a relevant field
  • Experience in RNA/DNA biochemistry
  • Excellent communication skills and good team spirit
  • Ability to solve problems independently
  • Fluent in English (spoken and written)

We offer

  • An international and vibrant working environment
  • Part time technician support
  • Competitive stipend or salary
  • Training opportunities

IMB is an equal opportunities employer.
