The Joyce lab studies how chromosomes are functionally organized and folded in 3-D space and time. Our primary goal is to understand how the structure and position of chromosomes within the nucleus is established and inherited across cell divisions, and how dysfunctional organization contributes to genome instability. To this end, we develop and utilize technologies to visualize chromosomes and subchromosomal regions at single-cell resolution and in a high-throughput fashion. Our research takes advantage of both Drosophila and mammalian systems as models for chromosome function, which allows us to directly address the conservation and health relatedness of the mechanisms we discover.
1. Spatial organization of the epigenome
2. Regulatory logic underlying condensin-mediated chromatin folding
3. High-throughput screening for novel pathways important for genome organization
4. Impact of aging on 3D organization
