Exploring cancer genomics

As a computational biologist, my research focuses on understanding the mechanisms of cancer initiation, progression, and prognosis through developing and utilizing computational methods.

My recent research areas include:

  • Identifying driver mutation, etiology, mechanism, and heterogeneity in human and mouse cancer genomes
  • Ultra-sensitive detection of cancerous and precancerous lesions using somatic mutations
  • Developing innovative and integrative open-source computational software for analyzing genomics data
  • Accurately interpreting complex genomic variants by haplotype-aware annotations

Current research

Cancer Genomics & Tumor Evolution

Next-generation sequencing (NGS) has become widely accessible in research and clinical laboratories. By using whole-genome, whole-exome and transcriptomes sequencing, we can detect various types of variants.

Ultra-Sensitive Detection of Mutations in Tumor and Normal Tissues

We’ve conducted innovative studies aiming to expand our detection limits to very-low-frequency (<5%) mutations, which are important for cancer early detection and residual disease monitoring.

Tumor-Specific Neoantigents for Immunoprofiling

We designed the Christmas Light Plot (CLP) for easy visualization of identified neoantigens. The CLP incorporates pre-defined criteria for neoantigen prioritization.

Mutational Landscapes in Preclinical Models

Analyses of mouse somatic mutations pose a unique challenge due to the diverse genetic background in GEM and mouse stromal contamination in PDX models.
