Colorectal Oncogenomics Group

Discovering the causes of colorectal cancer, reducing its incidence, and improving patient outcomes.

Our research includes the identification and investigation of clinically and biologically relevant subtypes of colorectal cancer (CRC), including both familial and non-familial CRC, that can be identified through genetic, epigenetic, somatic and histopathological characterisation of CRC tumours and their pre-malignant lesions (polyps).

Key research areas
  • Identifying novel genetic risk factors for CRC.
  • Improving our understanding of major CRC-related diseases, such as Lynch Syndrome and Serrated Polyposis Syndrome
  • Identifying biomarkers of risk and poor prognosis in CRC.
