Higher Degree by Research: Ms Janitha Iddagoda

Screams of Allergy vs Whispers of Tolerance

Ms Iddagoda’s research explored shellfish allergies, which affect millions worldwide. By studying patients who reacted differently to prawn species, she found that while IgE antibodies (the immune system’s “screams of allergy”) could not fully explain the reactions, IgG antibodies (the “whispers of tolerance”) revealed protective potential. Her research highlights the value of combining IgE and IgG profiling to improve diagnostic accuracy. This complementary approach may reduce reliance on risky food challenges and support safer, more precise allergy diagnosis.
On top of her win, Ms Iddagoda also captured the audience’s vote, earning her the People’s Choice award.

She went on to represent JCU in Singapore at the 3MT Final competition at JCU Townsville on 20 August 2025.

Gesturing for Order: How Singapore Teachers Use Their Hands to Manage Classrooms

Alumni Mr Chen’s qualitative study explained how Singapore primary school teachers use gestures, such as raising a hand or folding arms, to manage classroom behaviour. His study showed that non-verbal cues are effective tools, especially when reinforced by strong teacher-student relationships. These findings could inform teacher training on non-verbal classroom strategies.

The Same but Different? Community Structure on Heavily Modified Coastlines
