Our lab focuses on studying the organization and dynamical motion of chromosomal and plasmid DNA. While being intimately involved in genetic function, the packaging and arrangement DNA has operational effects that are not well understood at present. Errors in gene expression, besides arising from mistakes in the code itself, could also manifest by macromolecules that over-twist or over-stretch the DNA, problems in packing within the nucleus, long-range interference between genes, and so on. While challenging to address, these questions have the potential to define a new paradigm for our understanding of how living cells function.
