  Expertise and Research Interests

MicroRNAs (miRNAs) and the regulatory networks

MiRNAs are a class of endogenous regulatory small noncoding RNAs. At least 30% protein-coding genes are regulated by these tiny molecules. Using deep sequencing technology, we aim at developing the computational pipeline to analyze the miRNA expressions. Then, we try to develop network-based multi-layer association analysis methods (funded by NSFC) to identify the miRNA sub-networks regulating the cell phenotypes or diseases.

Complex biological networks

We are very interested in developing new theories and methods to establish the association (may be casual) between network states and cell/disease phenotypes. It is expected that we can use network states to explain or predict the disease occurrence and progression. We are also interested in developing new tools integrating gene expressions, biological networks and literature information, such as network clustering-based gene set analysis, gene function prediction and the simplified equivalent model of biological networks.

Developing the integrative computational platform and database for angiogenesis, inflammation, etc

Lab-mates have developed dozens of software and databases in network analysis, pathway analysis, literature mining, association analysis, etc. For better maintenance and broader use of these resources, we are developing flexible computational and storage platform to achieve the integration. We welcome the students with good software engineering/programming background to join our team.
