Nothing fishy about Krish’s winning 3MT presentation

Judging Chair Professor Lee Smith (DVC Research) congratulates 3MT winner Krish Gnanapragrasam

Topics ranging from the future of cruise tourism and the detection of a new species of irukandi jellyfish to developing an effective vaping cessation program were all part of the 2023 instalment of Griffith University’s Three Minute Thesis (3MT) presentation final held at South Bank campus in early September.

Twelve current PhD confirmed candidates, three from the University’s four Academic Groups, presented their research study summing up years of work of more than 80 thousand words into a succinct three minute ‘elevator pitch’ to the three-person judging panel.

In the end it was a passionate three minute explanation of his country’s overfishing problem in his native Sri Lanka which saw Griffith Business School PhD student Krish Gnanapragasam impress the judging planel to take out the top award as well as the audience-voted People’s Choice Award.

Professor Lee Smith (DVC, Research) remarked the judging panel found Krish had a clear articulation of a world-wide issue supported by a compelling visual slide. The judges also noted how Krish had excellent audience engagement offering them a clear description of the research being undertaken and potential impact outcomes.

Krish, who has spent many months in his native homeland talking to local fishing communities about overfishing, is developing new ways to stem the growing threat of dwindling fish stocks in south Asian waters.

“I lived in a place in the north of Sri Lanka where now I go back and it’s all changed. There are smaller fish populations and communities, which rely on this commodity, are hurting. So I really want to do something to my community and to my country. So that’s the real engagement and motivation in doing this research project.”

Krish now heads to the 3MT Asia-Pacific Final in October looking to become Griffith’s first ever winner of the regional decider.
