Image: 3D structural model of the genome in a human fibroblast nucleus. Model generated using our Chrom3D software, from Hi-C and lamin ChIP-seq input data to infer chromosomal interactions and positioning of chromatin domains towards the nuclear periphery. Each chromosome is distinctly labeled.

Ongoing research

  • Interplay between genomic organizers such as the nuclear envelope, LADs and TADs on nuclear architecture in stem cells and cancer cells
  • Mechanism of formation and disassembly of TAD cliques
  • Role of histone variant H3.3 on the radial organization of chromatin
  • Computational methods for 3D genome modeling
