Spatial / Architectural Epigenetics

Members of the Spatial/Architectural Epigenetics Interest Group Section are interested in the following questions: How is the genome is configured at various length scales?  How is chromosomal topology influenced by chromatin modification and nuclear factors? Conversely, how does chromosomal topology impact transcription factor function, gene expression, and other nuclear processes? How are genes positioned within the nucleus with regards to nuclear landmarks, and what is the mutual relationship with gene expression? We use genomic tools, various imaging technologies as well as genome and epi genome editing in diverse cell systems and organisms to address these questions.
