1. Please give a summary of your research.

In Australia, one in two men and women will develop cancer in their lifetime. We know that approximately 95% of new drugs fail during clinical trials after positive results during lab testing and animal model pre-clinical phases, creating a bottleneck of ineffective drugs. The biological differences between animals and humans limits the predictability power of pre-clinical models. The reduction and replacement of animals in research requires models that should mimic the natural human tissue environment.


Traditional methods for cancer research use cells grown on a two-dimensional surface, such as plastic or glass, which does not replicate human biology because humans are not two-dimensional. This is a major issue that has hindered cancer research for decades. I am developing new three-dimensional technologies for cancer research, using cancer cells grown inside of a jelly-like material (a hydrogel). These three-dimensional models are like “mini-tissues”, that are able to provide a more realistic environment for researchers to study cancer. This research will benefit Australia by placing it at the forefront of cutting-edge cancer research technologies, and by providing a new method for drug companies to test new cancer treatments. This could lead to a greater speed to market, greater drug accuracy in humans, and will reduce drug testing in animals. These three-dimensional “mini-tissues” open the way for a new generation of cancer research and will result in better testing, which will result in better health outcomes for patients. This is the future of cancer research.
