Recent technology advances in genome sequencing and whole genome profiling have facilitated the generation of massive amounts of multi-layer omic data. Sequencing a human genome will soon become a common task. A new challenge is how to make sense of such a huge amount of data especially when thousands (or even millions) of individual genomes are being explored. This is a bottleneck in understanding our genomes, eg. the molecular mechanisms of genetic diseases, and make use of this knowledge to better our health and wellness. Deriving biological insights from high throughput and/or large data sets requires data intensive and sophisticated analyses in which methods in data science driven by biological domain expertise are the key tools.

I am broadly interested in interpreting high throughput biological data using computational approaches. My current research agenda focuses on exploring computational, statistical and machine learning techniques that integrate multiple large-scale omic datasets to understand the human cancer genomes, including:
  • Tumor heterogeneity and evolution: Using whole genome, whole exome, and targeted DNA sequencing of temporal, multi-regional, intra- and inter-patient, and xenograft tumors, we seek to understand how cancer evolves, metastasizes, and resists to therapies [1-3].

  • The role of long non-coding RNAs (lncRNAs) in cancers: Utilizing gene expression profiles (eg. RNA-Seq, microarray), epigenetic signatures (eg. Chip-Seq), RNA-protein interaction data (eg. RIP-Seq), we discover lncRNAs that are potential cancer drivers/biomarkers of tumor progression, metastasis and clinical outcome, and subsequently characterize their function and mechanism in cell line and xenograft models [4-7].

Tools/databases that I have developed:
  • ClonEvol: Inferring and visualizing clonal evolution in multi-sample cancer sequencing
  • Allerdictor: a fast and accurate sequence-based allergen prediction tool employing text classification approach with support vector machine
  • Alternaria Genomes Database: a comprehensive resource for a fungal genus comprised of saprophytes, plant pathogens, and allergenic species
