My lab has active areas of research in virus-induced gene silencing, geminivirus-host interactions, and inabiotic stress. Long-term goals are to understand how geminiviruss, which are DNA viruses that transcribe their genes in plant nuclei, interact with plant gene silencing pathways, and to be able to harness these viruses for use in the functional genomics of crop plants. A second long-term goal is to understand how modulation of intracellular levels of calcium in the endoplasmic reticulum affects root growth and stress tolerance.
