Eukaryotic genomes are packaged as chromatin within the cell nucleus. Chromatin has a multiscale three-dimensional architecture varying from nucleosomes, loops, topologically associating domains to chromosome territories. The three-dimensional organization of chromatin within the nuclear space has been linked with genome function like regulation of gene expression and other DNA associated processes. Although application of various methods continue to provide fine details of chromatin architecture but the principles governing the three-dimensional organization of chromatin are just beginning to unravel. We are interested in understanding the role of chromatin-associated proteins in regulating chromatin organization at different genomic and special scales, from nucleosome positioning/accessibility to chromatin topology. To address this problem we are using an interdisciplinary approach including protein biochemistry/biophysics, genome wide sequencing based methods (like ChIP-seq, Chromosome conformation capture, MNase-seq and RNA-seq), mass spectrometry to polymer modeling.
