  • Minimally invasive and image-guided therapies
  • Neuroendocrine tumours

Research Foci:

  • Health services outcomes-based research
  • Processes of care and outcomes in neuroendocrine tumours

Research Summary:

The focus of Dr. Hallet’s research is on conducting health services population-based research to examine processes, patterns of care and outcomes hepato-pancreato-biliary malignancies.

In particular, Dr. Hallet is dedicated to improving care and outcomes of neuroendocrine tumours by identifying and establishing enablers to timely diagnosis and effective management.

She is also working on implementing and evaluating outcomes of pre-operative 3-D planning and intra-operative navigation programs for liver surgery.
