Overview

I am interested in developing statistical and computational methods for analyzing big and complex data, particularly high-throughput genomic data. I apply these tools to study gene regulatory programs in development and diseases. My research group develops methods for analyzing genome sequences, transcriptome, regulome, epigenome, and single-cell genomic data. We also develop user-friendly software tools, database and web servers to deliver the state-of-the-art data analysis methods to scientific community. We collaborate with biomedical investigators to apply our tools to decode gene regulatory circuitry in stem cell, cancer and other diseases.
