My interest is biotechnology for plant research. My graduate work focuses on Grapevine fanleaf virus and its potential to be a vector for grapevine. Viral vectors can specifically knock down mRNA or express proteins in plants, and these functions make viral vectors useful tools to understand plant biology. Specific areas of my research address the identity of the GFLV silencing suppressor, the properties of the GFLV satellite RNA, and ways of validating viral vectors for grapevine.
