Research Projects: 

The current research in my lab is directed to understand the establishment and maintenance of histone modifications in plants, their roles in regulating gene expression and development, and how they have contributed to the evolution of gene and genome functions. We use Arabidopsis and rice as model systems and employ a wide range of approaches, including genetic, molecular biology, biochemistry and genomic tools such as high-throughput sequencing and high-density tiling microarrays.
