Research Focus

My research focuses on the application of physics and informatics to cancer and healthcare research. I lead three distinct research groups. The first, Neutron-Induced Carcinogenic Effects (NICE), studies the production and toxicity of non-therapeutic neutrons in radiotherapy. This fundamental physics and radiobiology research involves Monte Carlo modelling and radiation detection. It is carried out with collaborators in government and industry. The second group, Radiation Oncology Knowledge Sharing (ROKS), is a translational research initiative that aims to improve the outcomes of radiation oncology patients by learning from data. The third group is known as the Opal Health Informatics Group (O-HIG), which I co-lead with Dr. Tarek Hijal and co-founded with Dr. Hijal and the late Prof. Laurie Hendren from Computer Science at McGill University. The O-HIG is the team behind Opal, an award-winning patient portal that provides patients with their healthcare data, collects patient-reported outcomes from them, and provides patients and clinicians with a virtual waiting room.
