Research Interests

My bioinformatics lab focuses on three primary research areas: (1) develop bioinformatics software tools, (2) build and maintain biological databases, and (3) conduct data analysis and data mining to address interesting biological questions. Current tool developing is mainly geared toward transcriptome data generated by next-generation sequencing, and we emphasize data cleaning, data integration, data visualization, and data mining.

My general research interest is to use a computational biology approach to understanding gene expression regulation and to elucidate their underlying biological mechanisms. My research is aimed at exploring alternative promoter usages (APU), alternative splicing (AS) and alternative polyadenylation (APA), and advancing our understanding of these alternative processes in mRNA transcription production, using various bioinformatics tools. It is clear that these alternative processes are key mechanisms for the creation and regulation of mRNA variants expressed from a single gene, allowing for variation in mRNA levels and in the functionality of the resultant proteins and non-coding transcripts. Currently, we are using Chlamydomonas and Arabidopsis as the model organisms for APU, AS and APA study. In addition, we are working with many other interesting bioinformatics projects, including eukaryotic gene prediction and genome annotation, cDNA assembly and clustering, genome re-sequencing, and genetic marker databases among others.
