Research Interests

My research work involves computer-based analyses of DNA sequence information. I am interested in the genetic mechanisms that affect plant genomes, including tandem duplications, transposable element-mediated gene duplications, and intron loss through reverse transcription. My primary work at present involves comparing the genomic sequences of the japonica and indica subspecies of rice.
