My lab studies RNA processing in plants, with an emphasis on mRNA 3' end formation and polyadenylation. The approaches we take are multi-faceted, and include genetic, molecular, and biochemical ones. The specific projects being pursued revolve around questions pertaining to mehanisms of mRNA 3' end formation, and to the connections between this process and regulatory events. Extensive use is made of the model organisms Arabidopsis thaliana, Escherichia coli and Saccharomyces cerevisiae.
