Stephanie Coffman


I received my Bachelors of Science from University of California, Fresno in Molecular, Cellular and Developmental Biology. As an undergraduate I worked at the USDA:ARS, where my work focused on virus discovery in the Glassy Winged Sharpshooter, the main vector of the bacteria, Xylella fastidiosa, which causes Piecre disease in grapes.

I began graduate school at UCR in the Genetics, Genomics and Bioinformatics program in Fall 2010 under the mentorship of Dr. Shou-wei Ding. My research focuses on understanding the genetic mechanisms that function in viral innate immunity using the model system Caenorhabditis elegans by utilizing a transgenic strain that contains a modified, genomic RNA sequence from Flock House Virus (FHV), a prototypical (+) sense RNA virus. This modified FHV transgene replicates to low levels in the wild-type worm, but is able to replicate to high levels when the worm's innate immune system has been genetically compromised. Furthermore, the transgene contains a GFP reporter that is replicated by the viral RNA-dependent RNA Polymerase and acts as a visual read out for viral replication. This unique system allows for viral replication to be studied in a living animal and gives us access to a plethora of powerful genetic and molecular tools that have made C. elegans such a successful model system. My research utilizes forwards genetics as a discovery tool to find novel genes that function in innate immunity and video bioinformatics to learn about the the dynamic sub-cellular localization of viral replication and innate immunity pathways that target RNA viruses, such as RNAi.
