The University of Wollongong researcher is studying data from weight loss studies at the university - and elsewhere - in order to design better and more effective diets.

"One of the big issues with weight loss of course is that people have trouble sticking to diets," Professor Batterham said.

"So we're looking at the weight loss trials taking place at Wollongong university to develop a model on why people drop out - and why they stick with diets.

"We're using data mining to also look at data from other studies, and ultimately will be looking at designing ways to develop more tailor-made diets for people so they're more likely to want to stick to them."

Prof Batterham is among 10 of the university's bright minds, who will be showcasing their groundbreaking research at the 2019 Big Ideas Festival this Wednesday.

Each will present a 10-minute talk on their research at the festival which will be held from 5pm to 9pm in the university hall, and live-streamed on the UOW Research Facebook page.

Other speakers include environmental health expert Thomas Astell-Burt, who will discuss how urban greening can keep us out of hospital.

Finance expert Millicent Chang will tell mum and dad investors how to make sound decisions about their superannuation and Karen Charlton will explain how 'purple is the new black' when it comes to foods for better brain health.

Education specialist Sarah O'Shea will discuss her research on how to help students from low socio-economic backgrounds, Aboriginal and Torres Strait Islander students and those from rural and remote areas thrive at university.

And Victoria Traynor will outline her mission to give nurses the skills they need to assess and treat patients with delirium.

Internationally renowned molecular biologist Professor Justin Yerbury will also present on his latest research into motor neurone disease.

Everyone is welcome to attend the event - held once every two years - which will also feature interactive research stalls as well as food and entertainment.
