My research is focused on developing bioinformatics approaches for analysis of massive genomic and high-throughput sequencing data, and using these approaches to systematically investigate the variation and dynamics of transcriptomic regulation within human populations, in response to environmental stimuli, development, and diseases.

Areas of Expertise

  • Single-cell data analysis
  • Design and application of computational methods for high-throughput transcriptome data analysis, such as microarray, RNA-Seq, SELEX-Seq and CLIP-Seq
  • Comparative genomics and molecular evolution
  • Population genomics and genetic variation
  • Statistical prediction model
  • Non-coding RNAs (microRNA and siRNA)
  • Post-transcriptional regulation (such as alternative splicing)
