research interest

we study rna biology and epigenetics in plants, specifically focusing on: 1) mechanisms and biological functions of rna regulation in plants; 2) mechanisms of transgenerational epigenetic inheritance in plants; 3) roles of rna regulation and epigenetics in the formation of important agronomic traits in crops.
