Presentation

Inspired by the functional diversity among the genetically identical cells of an organism, our goal is to understand how cells can interpret their genome in a particular way to establish their cellular identity. To this end, we study the mechanisms that cells use to form and maintain cell type-specific chromatin patterns along their genome. As these patterns span multiple scales from a few modified histones to micron-sized subcompartments, we investigate them using complementary techniques from single-molecule biophysics to live-cell imaging and computational biology.
