Brynn Mackie is a fifth year QUT student studying a double degree in Mathematics and Biomedical Science. She’s passionate about combining both fields to advance medical research, especially in areas like cancer and neurodegenerative diseases.
We caught up with Brynn for a Q&A to explore what she studies, why maths inspires her, and the opportunities she sees for students in the field.
What got you interested in mathematics?
I’ve always loved how maths can break complex problems into patterns and models. At first, maths and biomedicine felt like two separate interests, but once I started studying at QUT, I realised how well they work together. I’m now focused on medical mathematics, especially mathematical oncology — using computational models to understand how cancers grow and respond to treatment. One day, I hope to help improve the five-year survival rate of brain cancer and contribute to better treatment options for patients.
What’s been the highlight of your studies so far?
A major highlight was taking part in the Vacation Research Experience Scheme. I spent 10 weeks modelling brain cancer growth in response to a new drug treatment and exploring ways to optimise outcomes. I presented my research to peers and even travelled to London to showcase it internationally. That experience confirmed my passion for research and my desire to help tackle debilitating diseases.
What advice would you give to someone thinking about going to uni next year?
Get involved in student clubs early! I joined clubs like the Mathematics Society and Women in Maths club in my third year, and I wish I’d done it sooner. I was president of the Women in Maths club, which taught me so many valuable skills — time management, event organising, professional communication — and introduced me to an amazing, supportive community. Plus, we have craft days in the gardens, which is always a highlight!
What is your biggest goal?
Advancing brain cancer treatment. It’s a cause close to my heart and something that affects many Australian families. I want my work to make a real difference.
Where do you think maths can take students?
Pretty much anywhere! Lots of maths careers don’t even have 'mathematician' in the job title. Graduates become analysts, consultants and problem solvers across industries like sport, health, business and technology. If you’re curious, check out the Australian Mathematical Sciences Institute (AMSI) — it shows just how diverse maths careers really are.
