ecDNA Prevalence Across Multiple Cancer Types
A major cause of cancer treatment failure is the development of therapy resistance in tumors, which evolve by accumulating tumor-promoting mutations and modified chromosome structures. Our lab addresses this through computational and statistical analysis of large-scale biomolecular data — centered on extrachromosomal DNA (ecDNA), work spanning long- and short-read sequencing, single-cell and spatial multiomics, FISH validation, and structural variant analysis, alongside collaborators across cancer biology, epigenetics, structural biology, bioimaging, and tumor microenvironment research.

Breast cancer subtypes follow very different paths after chemotherapy given before surgery, leaving behind distinct patterns of residual disease — a step toward subtype-specific follow-up treatment.

The first pan-cancer map of ecDNA amplification, showing these circular DNA structures are far more common than once thought — and that they predict worse outcomes as tumors advance.

Extends ecDNA's reach beyond the cancers we usually study, showing it also drives the earliest steps of Barrett's esophagus turning cancerous.
