Harold E. Johns Studentship Program in Medical Physics

The following details are relevant for the Harold E. Johns Studentship Program for the 2017/18 application cycle.


Dr. Harold E. Johns (1915-1998) was a Canadian physicist noted for his extensive contributions to the field of medical physics. Dr. Johns invented and developed the Cobalt-60 machine which had an immediate impact on cancer survival rates, enabling radiation medicine professionals to treat deep-set and difficult to access tumors. The machine represented a major technological advancement and his work launched the development of cobalt therapy for the treatment of cancer, which is still the primary mode for radiation treatment in many developing countries that lack access to more modern therapies. Dr. Johns’ work was influential in the early development of CT scanners and the definition of mammographic imaging, and he also did significant work in showing the DNA damage in cells exposed to ultraviolet rays. His book, The Physics of Radiology, is considered to be the premiere text in the field of medical physics.

Dr. Johns garnered many awards and accolades throughout his career. He is an Officer of the Order of Canada, a recipient of the Queen's Jubilee Medal, and was the first to receive the Medal of Honour from the Canadian Medical Association – the highest honour that the Association can bestow on a person who is not a member of the medical profession. Dr. Johns was a true pioneer in the field of medical physics, and the Harold E. Johns Studentship Program is named in his honour.

The objective of the Harold E. Johns Program is to promote interest in the field of medical physics among undergraduate students, and to encourage these students to continue their studies and pursue careers in the field of medical physics in oncology in the Ontario cancer system.

Qualifications and Basis of Award

In order to be eligible for a Harold E. Johns Studentship Program, an applicant must be:

  • An undergraduate student enrolled in a physics program or a program of a related discipline at a recognized university who is returning to undergraduate studies in the term following the studentship

  • A student in their final year of undergraduate studies or who has recently completed their undergraduate studies in a physics program or program of a related discipline and can provide proof of application and/or enrollment in a graduate program in physics or biophysics at a recognized university at the time of application
  • This is a one-time award; applicants will be considered ineligible if they have previously held a Harold E. Johns Studentship

Studentships are awarded on the basis of:

  • Academic achievement (minimum GPA of 3.30, as calculated according to percentage to GPA conversion scheme of the applicant’s university)
  • Demonstrated interest in the field of medical physics


Approximately four (4) months.


A total of up to 13 awards are offered across Ontario, one (1) in each of the following Regional Cancer Programs (RCPs) located at the following centres:

  • Princess Margaret Cancer Centre (Toronto)
  • Odette Cancer Centre at Sunnybrook Health Sciences Centre (Toronto)
  • Juravinski Cancer Centre (Hamilton)
  • Grand River Regional Cancer Centre (Grand River)
  • Cancer Centre of Southeastern Ontario (Kingston)

Studentship Description and Requirements

Each studentship recipient will be matched with a supervisor at the centre at which they are completing their studentship who they will work closely with on a specific project/series of projects for the duration of the studentship.

At the end of the studentship term, each studentship recipient is required to complete a scientific report of approximately five (5) pages in length which must include the following sections:

  • Project Description ( including: abstract, introduction, methodology, results, discussion, conclusion, references)
  • Self-Reflection (including: experience impact, future educational and career aspirations)

Any one of the following Report formats is acceptable provided it contains sections outlined above:

  1. A set of slides summarizing the work, as presented to the host institution at the conclusion of the project
  2. A report, as required by the student's home university (e.g. COOP internship programs)
  3. A draft manuscript written in a journal publication format with the self-reflection section attached

Reports are to be submitted by the award recipients to the Cancer Care Ontario Radiation Treatment Program mailbox at

Only electronic copies will be accepted.
