We’re a translational research team. Our approach is to identify specific situations where advances in science and technology can be exploited to overcome the current challenges in the clinical management of gastrointestinal (GI) cancer. We focus on three areas:

  1. Realtime diagnostics (Lead: Iain Tan), non-invasive testing with circulating cell-free DNA;
  2. Metastasis (Lead: Clarinda Chua); and
  3. Immuno-oncology (Co-Lead: Iain Tan, Koo Si-Lin).

Our approach uses multi-omics analyses of colorectal cancer sets (WGS / WTS / whole proteome / metabolomic / microbiome) with one of the largest pan-omic sets of GI cancers globally. We use patient-derived tumour models for studies in metastases and immune cells (tumour-infiltrating and peripheral immune cells) with corresponding patientderived tumour models for studies in immunotherapy. We are performing window-of-opportunity clinical studies with pre-op immunotherapy and studies towards neoantigen vaccine therapy. Our laboratory has published widely, with publications in Nature, Nature Genetics, Nature Medicine, Science Translational Medicine, Immunity, Annals of Medical Oncology, among others. We have multiple national research grants and are involved with several national research programmes. We lead several investigator-initiated trials and also participate in global Phase 2/3 trials.
