Graduate work was focused on variant non-catalytic RNA polymerase subunits and their surprising role for the functional specification of RNA silencing RNA Polymerases IV and V in the small RNA directed DNA methylation pathway, as well as the role of DNA demethylation in multi-megabase epigenetic silencing in the laboratory of Craig Pikaard.
Undergraduate research project included map-based cloning and characterization of mutants from a forward genetics screen for genes regulating Innate Immunity in the laboratory of Xinnian Dong.
