Highlights from the 2014 COMP Young Physicists Competition

The Canadian Rockies in late spring provide an unlikely backdrop for a gathering of medical physicists, yet that is exactly what Banff offered in 2014. The Canadian Organization of Medical Physicists chose the mountain town for its annual scientific meeting, and delegates arrived from Canadian hospitals, American cancer centres and a substantial contingent from Australia and New Zealand. Among the most energising elements of the programme was the Young Physicists Competition, a long-running fixture designed to give graduate students and recent graduates a serious scientific stage.

Delegates from Sydney and Brisbane brought students whose abstracts had cleared regional review. The competition offered those students something the home circuit rarely does: a judging panel of senior hospital physicists from across North America, immediate feedback from researchers whose names appear on the citations they study, and the chance to test their findings against the scrutiny of an international audience. For many, it was the first time their work had been treated as conference-grade science rather than as practice.

The Banff setting softened the intensity without diluting it. Evenings around the Banff Centre allowed finalists to relax with delegates over posters and refreshments, while days were tightly packed with parallel sessions, vendor demonstrations and committee meetings. The competition slotted into the same rhythm, and judges made clear that no accommodation would be made for the candidates' junior status. The finalists who rose to that expectation left Banff with experience that would travel with them into residency, PhD programmes and clinical posts.

The structure of the competition and its judging panel

Judges for the competition were drawn from the COMP membership and included clinicians, hospital-based physicists and academic researchers. Scoring was weighted toward methodological soundness, novelty and the candidate's ability to contextualise findings for an applied clinical audience, an attribute increasingly valued in Australian training programmes where ACPSEM TEAP competencies emphasise translational thinking. The format required finalists to deliver a ten-minute talk followed by five minutes of questions, with audience participation encouraged.

The chair of the panel, a senior medical physicist with experience on International Atomic Energy Agency committees, noted in the opening remarks that the quality of submissions had risen noticeably since the previous year's meeting. Several entries had already been submitted to peer-reviewed journals before the competition, a sign that student-led projects were maturing faster than in earlier cohorts. Past recipients had used the recognition to strengthen applications for clinical residency posts and PhD programmes, and several had gone on to publish in journals such as Physics in Medicine and Biology.

Profiles of the winners and their research

The first-place prize was awarded to a graduate student whose project explored the use of high-intensity focused ultrasound as a non-invasive alternative for targeted drug delivery in solid tumours. The work combined acoustic modelling with phantom validation, and the student handled technical questions from clinical physicists with a confidence that impressed the panel. Colleagues from the Central Coast Cancer Centre in Gosford noted afterwards that the methodology could be adapted for pre-clinical work in their own laboratories.

Second place went to a candidate whose submission focused on audit methodologies for clinical dosimetry, drawing on a multi-institutional dataset that included data shared by Australian hospitals participating in the ACPSEM dosimetry audit programme. The presentation covered intercomparison results across nine centres, including work done at the Olivia Newton-John Cancer Centre in Melbourne, and examined systematic biases in small-field output measurements. The candidate's careful treatment of uncertainty budgets was singled out by the judges as exemplary for a student-level project, and the work aligned closely with broader discussions at the meeting.

Third place was awarded to a project on automated quality assurance for linear accelerators, developed in collaboration with a Canadian cancer centre. The student had built a Python-based analysis pipeline that flagged deviations in daily output checks and reduced manual review time considerably. Engineers at the Australian Synchrotron in Melbourne, who attended the meeting to present parallel work on beam diagnostics, approached the finalist afterwards to discuss potential collaboration.

Themes across the finalist cohort

A striking number of submissions dealt with image-guided radiation therapy, particularly the integration of cone-beam CT with surface-guided systems for breast and chest wall treatments. Several candidates had developed in-house algorithms to flag patient setup errors before imaging, reducing unnecessary dose from verification scans. Australian delegates were particularly attentive to this work because of ongoing efforts in regional centres such as the Alan Walker Cancer Care Centre in the Northern Territory to extend modern IGRT techniques to remote populations.

Monte Carlo simulation was another recurring theme, with finalists using GEANT4, EGSnrc and PENELOPE to model complex scenarios including electron cutout factors and proton range uncertainties. One student presented a streamlined method for variance reduction that cut simulation times by nearly forty per cent, drawing comparisons with approaches being trialled at the Peter MacCallum Cancer Centre in Melbourne. Dosimetry audit work also featured prominently, and the abstract session on dosimetry audits and intercomparisons attracted the strongest audience of the meeting. ARPANSA's guidance documents were cited by finalists working on radiation protection and shielding, with a representative from the agency hosting an informal discussion about harmonising Australian and Canadian approaches.

Connections between competition work and clinical practice

Many of the projects presented in the competition were explicitly designed to address problems encountered in the finalists' home clinics, rather than purely academic exercises. One candidate described how a near-miss event involving an electron cutout had prompted a systematic review of all electron cutouts at her centre, and how the resulting dataset had been analysed as part of her graduate thesis. The judges commended this patient-safety framing, noting that it aligned closely with the incident-learning culture promoted by COMP and mirrored by ACPSEM safety and quality modules.

Another finalist had partnered with a regional cancer centre serving a large rural catchment to evaluate the feasibility of remote treatment planning. The project drew on the Australian experience of providing outreach services across vast distances, from Townsville to Hobart, and explored how standardised plan templates could reduce variation between sites. Mentors accompanying the finalists also benefited from the meeting, using the trip to renew contacts with research groups in Toronto and Vancouver, and at least one residency programme director from New Zealand attended with the explicit goal of recruiting finalists for clinical posts.

Legacy and career trajectories of the finalists

A surprising number of the 2014 finalists are now practising clinical physicists in Australian and New Zealand hospitals, working in roles accredited through the ACPSEM training programme. One of the second-place recipients took up a residency post at a Sydney cancer centre in the months after the meeting, and another relocated to Perth to join a proton therapy planning team. Several have published the work they presented in Banff, contributing to the small canon of student-led clinical physics research that informs departmental practice.

The competition also seeded longer-running research collaborations, including a multi-year study on lens dosimetry that grew out of a corridor conversation between a finalist and an ARPANSA representative. For the broader COMP membership, the competition remains a useful bellwether for the state of student training, and the 2014 cohort was notable for its translational bent, with projects almost universally anchored in concrete clinical problems rather than abstract physics. That posture, more than any individual prize, may be the competition's most significant export to graduates of physics training in the years since.

The stories, abstracts and judge commentaries from that year remain available through the conference archive, and the organisers continue to encourage physics students and junior trainees to explore the materials before submitting their own work to future editions. Practising physicists and educators are invited to share the archive with their trainees, recommend standout abstracts for journal club discussion, and consider nominating a junior colleague for the next round of the Young Physicists Competition.
