Project Outline

In principle, all cells derived from a fertilised egg have the same genetic information. However, in some animals, specific genomic regions are removed from somatic cells during development. Why parts of the genome are removed from these cells, but not from cells forming the gametes (germline), has long remained an open question. Using a small free-living nematode, this projects aims to find the molecular components involved in removal of 60% of the genome during development.

    • gene editing tools to generated mutant nematodes (e.g., CRISPR/Cas9)
    • generation of transgenic nematodes (e.g., tagging of specific proteins with fluorescent markers)
    • microscopy (e.g., time lapse videos, confocal microscopy)
    • bioinformatics (e.g., writing scripts in Unix, R and Python)
    • mathematical modelling (R, Python)
