Research Overview

A number of epigenetic regulatory layers are superimposed on the genome. In plants, small RNA regulators play a major role in the establishment and maintenance of epigenetic marks. We are interested in understanding the mechanism of small RNA biogenesis, their functions and their role in establishment of epigenetics using a number of model systems.
