Research focus:

  • ROKS (Knowledge Sharing in Radiation Oncology) - translational research
  • NICE (Neutron-Induced Carcinogenic Effects) - fundamental research
Short research description:

Knowledge Sharing in Radiation Oncology

  • This translational research is harnessing the power of data generated by previous radiation oncology patients in order to improve the experience, safety and outcomes of future patients. 

    The objectives of the ROKS group are:

    (a) develop knowledge-based and evidence-based radiotherapy treatments,
    (b) use data to improve the experience and outcomes of radiation oncology patients.

  • We use three methods to achieve our objectives. They are:

1.  by facilitating guidelines, policies and procedures written by experts,
2.  by learning from adverse events, and
3.  by learning from data.

  • The ROKS research group currently comprises one PI (John Kildea), two M.Sc students (Ackeem Joseph and Logan Montgomery) and one research assistant (David Herrera). Our group is an integral part of the HIG (Health Informatics Group collaboration).
  • More information about the ROKS research group, including photos and presentations, is available on our homepgae.

Neutron-Induced Carcinogenic Effects

  • This fundamental research effort has as its goal an improvement in our understanding of the production and carcinogenic effects of secondary neutrons in photon-beam and proton-beam radiotherapy.
  • The NICE group is a collaboration between McGill, Canadian Nuclear Laboratories (Chalk River, Ontario), the Canadian Nuclear Safety Commission, and Detec Inc. 

  • We are investigating neutron carcinogenesis through a combination of measurements and Monte Carlo modelling. Our approach is similar to that of the European ANDANTE project but it underpinned by our neutron spectral measurement technique using the Nested Neutron Spectrometer and CNL's world-class radio-biological facilities at Chalk River.

  • More information about the NICE research group, including photos and presentations, is available on our homepage.
