Overview

My major research interest is to develop statistical methodology for the study of gene regulation. My current work involves developing statistical tools to detect genomic regions where protein-DNA interactions occur, to discover transcription factor binding motifs, and to identify interesting gene expression patterns. My long term goal is to establish effective and efficient statistical strategies that would allow us to decipher mammalian gene regulatory networks by synthesizing information from gene expression, protein-DNA interactions, protein-protein interactions, genome sequences, transcription factor binding motifs and existing knowledge on signaling and metabolic pathways. Knowledge of these networks will serve as the basis for us to understand human development and disease.
