Molecular Plant Virology
My molecular plant virology research is on a virus complex of Panicum mosaic virus (PMV) and its satellite virus (SPMV). For molecular genetic studies on the PMV/SPMV virus:host interactions we are using the model grass, Brachypodium distachyon. Our current research focus includes investigations into the mechanism by which SPMV capsid protein (CP) localizes to the nucleolus, how host proteins facilitate this trafficking, and how SPMV and PMV induce host responses to infection. My second area of research is the historiography of Tobacco mosaic virus (TMV) in the early 20th century in the United States. My research and writing on the history of plant virology has been incorporated into graduate and undergraduate courses.
I teach the following courses in the Bioenvironmental Sciences (BESC) Program: Pathogens, the Environment, and Society (BESC 314), Field Experience (BESC 484), and a Capstone Seminar (BESC 481). I am the Faculty Director of BESC Undergraduate Honors Program.
