Please login to favourite this article.

Careers in STEM don’t always follow a linear path and people don’t always know what they’re going to be when they grow up. Watch this career profile to find out about the importance of medical physicists in Australia, what they do and how they got there.

Medical Physicists are going to play a huge role in Australian cancer care in the future. As the revolutionary Particle Therapy begins to be established in Australia, people like Sean and his knowledge of both physics and medicine will be at the very forefront.

From studying physics in Western Australia, Sean has had a career working around the world, before settling in Adelaide to head up the state’s team of medical physicists working in cancer therapy.

Adelaide will build Australia’s first particle therapy facility, utilising protons to target cancer. This therapy can specifically destroy tumours with very minimal effects on surrounding healthy tissue.

In his role, Sean will be central to the development and operation of this revolutionary facility.
