Division of Mathematics for Cancer Evolution and Early Detection

The Division of Mathematics for Cancer Evolution and Early Detection uses mathematical modeling and sequencing data for understanding:

  • Tumor evolution and cancer etiology 
  • AI and machine learning applied to sequencing and imaging data for cancer early detection and monitoring of minimal residual disease
  • Statistical methods for cancer risk prediction and trial design
  • Bioinformatics for genomic data

Our Research Focus

Early Cancer Detection

Noninvasive cell-free DNA (cfDNA) blood tests and imaging have the potential to detect cancers years before conventional diagnostic methods.

Cancer Evolution

The sequential accumulation of genetic and epigenetic changes drives cancer. We provide mathematical models of the complete process of tumor evolution. These models can recapitulate a substantial proportion of the observed incidence in several cancer types.

Cancer Etiology

About two-thirds of the cancer-causing genetic mutations can be attributed to random errors that occur as our normal cells divide rather than to environmental, lifestyle and inherited factors.

Cancer Monitoring

The presence of circulating tumor DNA (ctDNA) post-surgery predicts recurrence. A ctDNA-guided approach to cancer reduces adjuvant chemotherapy use without compromising recurrence-free survivorship.
