Research Interests


The accomplishment of various genome sequencing projects, the avalanche of high throughput "omic'' data, and the increasing number of solved protein structures, have provided system-level measurements in model organisms. The conversion of the wealthy heterogeneous data to our understanding of the structure and dynamics of biological processes will only be possible by developing effective data-integration methods. My research aims at integrating and mining diverse high throughput data to extract biological insights and to address fundamental biological questions that would enhance our understanding of systems as a whole. This will be accomplished by designing statistically rigorous and physically sound models to integrate genome sequences, expression profiles, molecular interactions, and protein structures etc. My research interests also include Computational Systems Biology; Bioinformatics; interactions between pathogens and plant cells; and gene/protein interaction network in plant cells.
