Biography:

My principal research interest has been focused on control of plant development. During my Ph.D., I studied seed germination and dormancy in Arabidopsis and their regulation by various histone modifications. Since I moved to Cambridge, I switched toward transposons using rice as a model. Rise is a better model than Arabidopsis to study transposons because it has many more of them and more severe development phenotypes when transposons are misregulated. Based on these pieces of evidence, I hypothesize that transposons might play critical regulatory functions in rice development. To elucidate the role of transposons, I initially interrogated public transcriptomic data searching for active transposons. The preliminary analysis revealed that 1) the expression pattern of transposons is tissue- or developmental stage-specific and 2) transcriptional activities of genes harbouring transposon-derived sequences strongly correlate with those of the corresponding transposons. Currently several transposon-gene pairs are being examined for their mechanistic relationship employing genetic, biochemical as well as bioinformatic approaches.
