Professor Ralph N. Martins has dedicated the last 38 years to Alzheimer’s disease (AD) research and is widely acknowledged as a world leader in the field. His insight into this devastating disease has led to several ground-breaking discoveries, including the seminal discovery of beta-amyloid and its precursor, the amyloid precursor protein (APP) (while at Prof. Colin Masters’ lab) found in the brains of Alzheimer’s patients and now universally acknowledged as being fundamental to the molecular pathogenesis of AD.

Another landmark discovery has been identifying oxidative stress in the Alzheimer brain. Targeting beta amyloid and oxidative stress is now the focus of clinical research into prevention and treatment, and a target of the global pharmaceutical industry. Martins and his team have been at the forefront globally in developing non-invasive and cost-effective early diagnostics for pre-clinical AD. They have progressed a cutting-edge program of biomarker candidates for AD screening encompassing retinal amyloid imaging, proteomic and lipidomic analysis of blood and cerebrospinal fluid. Prof Martins and his team are also progressing a highly innovative program of therapeutic strategies and preventative interventions in pre-clinical AD. The reach and significance of Prof. Martins’ research is evidenced by more than 538 peer-reviewed publications (over 200 in the past 5 years), several in high-impact journals such as Nature, Lancet, the Journal of the American Medical Association, the New England Journal of Medicine, Molecular Psychiatry and Journal of Biological Chemistry. Over the last five years his publications have been cited over 30979 times, and he has an H-index of 88 (Scopus). Furthermore, in recognition of Prof. Martins’ outstanding achievements in AD research, he was awarded the highly prestigious Western Australian of the Year in 2010, the Western Australia’s Citizen of the Year (Professions) in 2011 and Officer of the Order of Australia in 2013.

Associate Professor Stephanie Rainey-Smith obtained a PhD in Neuroscience from King’s College London, under the supervision of Drs. Robert Williams and Marcus Rattray.
