The Metrology Research Centre at the National Research Council (NRC) maintains and disseminates standards of measurement – time, length, mass, temperature, etc. – to Canadian organizations (e.g. industry, university, government). The Ionizing Radiation Standards (IRS) group at the NRC is responsible for absorbed dose standards, ensuring consistency across Canadian radiotherapy clinics. In short, I study how to measure radiation dose with extreme accuracy, so that cancer treatments can be delivered more safely and effectively.
My research within IRS focuses on the development and validation of absorbed dose calorimeter systems for emerging radiotherapy delivery techniques (e.g. ultra-high dose rate / “FLASH” therapy). Designed for use in clinical settings, these calorimeters emphasize portability and ease-of-use while maintaining high measurement accuracy.
I’m also active in advancing the capabilities of electronic portal imaging device (EPID) dosimetry by assessing how accurately these ubiquitous flat-panel detectors can reconstruct patient dose in real time or post-treatment, enabling error detection during delivery and supporting adaptive radiotherapy.
In parallel, I am establishing a new primary method to determine the activity concentration of radioactive noble gases, which are key isotopes released from nuclear reactors, accidents, and weapons use, and are also important in medical diagnostics such as Xe-133 imaging for lung cancer.
