She received her Ph.D. from Duke University, Durham, North Carolina, USA, and completed postdoctoral studies in the Sainsbury Laboratory, Cambridge, UK, and the University of Cambridge, where she investigated genomic targets of RNA polymerase IV. Using plants as models, her laboratory studies the mechanism of RNA-directed DNA methylation, how epigenetic information is passed from parent to offspring, and how maternal and paternal epigenetic marks interact after fertilization.
