Dr. Fang has been deeply involved in the study of molecular pathogenesis of porcine reproductive and respiratory syndrome virus (PRRSV) for more than 20 years. Current research program is expending to other emerging/foreign viral pathogens. Her research interests have been focused on understanding the basic molecular mechanisms of viral pathogenesis, and applying the basic knowledge to develop strategies for the diagnoses, prevention and treatment of viral diseases. The laboratory has well established technologies and swine model system for vaccine and diagnostic assay development. Fang’s research has been supported by research grants from the US Department of Agriculture, National Institute of Health, National Pork Board and industry partners.
