Research Description:
With the emerging appreciation of precision medicine, the link of genetic and epigenetic perturbations to their phenotypes is vital. With the advent of CRISPR-mediated genome editing and high-throughput sequencing, we can both systematically perturb the genome and quantitatively measure their phenotypic effects. In the Hess lab, we are interested in both the development and application of these and other functional genomics technologies to address critical biological questions and improve human health. Using these cutting-edge genomics tools, we focus on three areas: (1) investigating mechanisms of drug resistance and response, (2) regulation of mammalian DNA repair, and (3) studying effectors secreted by bacterial pathogens.
