Infectious Disease Responses Laboratory

Spanning the themes of Infectious Disease, Immunity & Inflammation and Cancer in Medicine at UNSW, our research involves the molecular identification and subtyping of viral pathogens such as influenza and HCV, understanding their biological properties and mode of action at the molecular level, and the development of antivirals to respond to their infection. The technological approaches we develop allow us to characterise viruses (including oncoviruses) into different subtypes, develop specific treatments, and also help advance ‘omics’ and informatics approaches for their use in clinical practice.

A current research focus concerns the development and application of molecular based methods, particularly mass spectrometry, to improve the identification, characterization and responses to viruses that cause infectious disease and cancer. A particular focus has been to arrest the impact of the influenza virus. Influenza is responsible for as many or more deaths in Australia today than all individual causes of human cancers, with the exception of lung cancer. Furthermore, an estimated 15 percent of all human cancers worldwide are associated with viral infections. Improving our ability to identify and respond to such disease causing viruses is essential to reducing their burden on public health.

Recent work has involved the identification and development of new antiviral inhibitors to combat viruses associated with influenza and hepatitis by exploring their mode of action using experimental and computational approaches. We have also developed a new phylogenetics approach to improve our ability to study and better understand the evolution of viruses, with a view to reducing their impact. Innovative new mass spectrometry based methods and bioinformatics approaches and computer algorithms have been developed and employed to characterise influenza viruses, and other biopathogens, at the molecular protein level without sequencing.

A new structural biology approach employing a protein footprinting technology (also known by the acronym RP-MS) has also been developed in collaboration and applied to study proteins and complexes important to human vision. The impact of early onset oxidative damage on their structural integrity associated with cataract, a leading cause of blindness worldwide, has been investigated.

Head & Group Leader

Professor Kevin Downard has held professorial positions abroad and in Australia after completing postdoctoral studies and holding a subsequent academic position at the Massachusetts Institute of Technology. He has 30 years research experience in mass spectrometry, the past 20 years leading his own group in its application and development to advance discoveries in medicine.

Professor Downard is the author of over 100 peer-reviewed scientific publications, as well as two books, and he has received large research funding from the Australian Research Council and other sources. He has twice received international fellowships from both the Australian Academy of Science and the Japan Society for the Promotion of Science and is frequently invited to give keynote lectures at national and international conferences. He was the first Australian to be recognised for his research achievements with an award from the world's largest mass spectrometry society (ASMS) and convened both the national biennial MS conference in 2009 and the 2003 Sir Mark Oliphant Conference in Sydney. He has also been recognised by the Australian Academy of Science for his efforts to research and document the history of science as recipient of the Moran Award in 2006.

He collaborates with researchers at UNSW, greater Sydney, nationally and internationally in both academia and industry.
