My research team studies fundamental processes that regulate access of genetic information encoded in our DNA. We focus on histone proteins, exploring how chromatin — formed when DNA coils around histones into distinct structures along the genome — modulates the accessibility of the underlying sequence information. Functioning like a Google search engine for our genome, chromatin guides sequencing-specific factors to their target sites more efficiently amidst a sea of distracting information. By modulating the position, composition, and stability of histone-DNA complexes, chromatin structures block non-physiological binding sites and direct sequencing-specific factors to designated targets, thereby facilitating their precise cellular functions. We employ a diverse array of techniques, spanning biochemistry, genetics, genomics, computational biology, and structural biology, to unravel the principles governing gene expression and their impact on human health.
