The research field of our group is Computational Genomics and Bioinformatics, with a strong focus of mining large-scale high-throughput genomic data. We develop and apply computational techniques for integrating data of comparative genomics and functional genomics to study the structure, function, and dynamic of the human genome. In one direction, we investigate the emergence and subsequent evolution of species-specific genomic sequences; in the other, we study the complexity and dynamics of gene regulatory networks. The long-term goal and significance of our research program is to gain biological insights to the fundamental regulatory networks directing the developments of individual human tissues or organs (e.g., neurogenesis), and the genomic disorders and regulatory dysfunctions that are often associated with a variety of human diseases (e.g., neurodegenerative diseases).
