Biography & Research Interests

A fundamental question in virology is how RNA viruses pathogenic to humans, animals and plants successfully replicate and package their genomes in to stable virions for subsequent dissemination to new hosts to cause a disease. Consequently, the major focus of research in my laboratory is to unravel the complexity of the host interactome regulating viral RNA replication in mechanistic detail by coupling genetic and proteomics approaches. To this end, we are using three viruses having single-strand, positive-sense RNA genomes as model systems. These are plant infecting Brome mosaic virus (BMV) and satellite RNA of Cucumber mosaic virus (CMV) and Flock house virus (FHV) pathogenic to insects.  For more information on the current projects in the lab, please visit raolab.ucr.edu.
