    An Epigenetic Jungle
    A gibbon is swinging across a river within an epigenetic landscape, which regulates compaction and expression of our DNA. The arid desert illustrates loosely packed DNA containing actively expressed genes, whereas the tropical forest represents densely packed chromatin. The gibbon genome is similar to ours, but many regions were heavily rearranged during evolution. Still, even the rearranged genes keep their original epigenetic landscapes because the shuffling has occurred at boundaries between
  2. A Knitted Network of DNA

    A Knitted Network of DNA
    During division, cells disassemble their nucleus and release many independent chromosomes - but how are all those chromosomes enclosed in a single nucleus after mitosis? The protein BAF cross-bridges DNA strands, allowing the cell to 'knit' a network of DNA around the chromosome ensemble and guide the nuclear membrane along the surface. This drawing illustrates BAF as beads that link the DNA strands into a network. Congratulations to the Gerlich lab on this fantastic Cell paper!

    A Dynamic ESCRT for Splitting Membranes
    I'm so excited to share a drawing I made for my own paper recently published in Nature Cell Biology!  This artwork illustrates the dynamics of a protein machinery for splitting membranes. This machinery, called ESCRT-III, forms spirals that constantly exchange their building blocks with the help of a protein called VPS4. This remodeling allows the spirals to change their shape and constrict membranes until they split, for example in the final step of cell division that separates the emerging

    Nature Methods Cover - An Arrow Poison for CRISPR
    My new artwork on the current Nature Methods cover - what a great honor! Ouabain, a molecule traditionally used as an arrow poison in Africa, is used as a new selection method for CRISPR. Congratulations to the Doyon lab for a fantastic paper!
