Overview

Recent advances in microarray and sequencing technologies made the genome-wide profiling of DNA methylation and histone modifications feasible and scalable to cohorts containing hundreds or even thousands of samples. Large international consortia, such as the Encylopedia of DNA Elements, The Cancer Genome Atlas Project, the International Cancer Genome Consortium and the International Human Epigenome Consortium have systematically generated comprehensive epigenome-wide datasets on tissue samples and cell lines in human. These vast cohorts open unprecedented opportunities to study the genetic regulation, intracellular heterogeneity and disease progression at the molecular level, but they also bring up enormous challenges in data processing and analysis.

Major Research Directions

  • Computational methods for epigenome analysis: deconvolution, phylogenetic analysis and cancer cell-of-origin inference 
  • Epigenome-based biomarker discovery using machine learning methods
  • Integrative analysis of multi-omics datasets in several cancer entities (early-onset prostate cancer, CLL, AML, T-ALL, cholangiocarcinoma, giant-cell tumor of bone)
  • User-friendly software tools for processing and analysis of epigenomic data:
  • Reproducible bioinformatics, containerized scientific workflows and accessible deployment interfaces
