Dr Rajesh Ramanathan combines nanoparticles with light to achieve a wide range of biomedical applications. From sensing chemicals and bacteria, to healing wounds and imaging patients, his nanotechnology is at the forefront of biomedical science and its potential is endless. Winner of the 2019 Phillip Law Postdoctoral Award for Physical Sciences, Dr Ramanathan shared his journey to incorporate elements of nature into the design of nanoparticles for a wide range of biomedical applications. By shining a light on patients and nanoparticles, he can reveal their glucose levels, repair their wounds, and image their tumours.
With Dr Rajesh Ramanathan, we encounter a special example of a scholar exploring the knowledge base from traditionally separate field of scientific inquiry. First trained as a biologist, Rajesh combined his PhD work in materials science to consolidate expertise across the chemical, physical and biological sciences, enabling him to develop and contribute to research projects across disciplinary boundaries, leading work in the exciting new field of nanobiotechnology.
This year, the assessors of the Royal Society of Victoria’s Phillip Law Postdoctoral Award in the Physical Sciences worked diligently through the pile of applicants that grows, year on year, with the growth in Victoria’s remarkable pool of talent. It is an intensely competitive field of Early Career Researchers and, this year, our assessors simply could not find a way to separate the two lead applicants.
“Both have made – and continue to make – significant contributions to modern physics with different, substantial potential for application,” explained Dr Peter Baines, the Secretary of the Royal Society of Victoria and one of the assessors. Ultimately, the two lead applicants were ruled a dead heat.
The Society congratulates Dr Sumeet Walia and Dr Nishar Hameed on their joint win of the 2018 Phillip Law Postdoctoral Award for the Physical Sciences!
While antibiotics have reduced the global burden of infectious disease, these miracle drugs are no longer working against emerging “superbugs.” A recent report from the UK estimates that, by 2050, nearly 10 million people are likely to die from drug-resistant infections if the current trends persist. In response, Professor Elena Ivanova and her team have generated bactericidal surfaces that physically rupture bacterial cells in a few hundred seconds without harming animal cells. The rapidness with which they kill ensures that there is little opportunity for bacteria to adapt and become resistant. In the middle of a global antimicrobial resistance crisis, Professor Ivanova’s work provides hope that we haven’t yet lost the fight against superbugs!
