Emeritus Professor Michael Pender graduated from The University of Queensland in 1974 with First Class Honours in Medicine and a University Medal. Over the next six years he trained as a physician and neurologist at the Royal Prince Alfred Hospital and St Vincent's Hospital, Sydney, and became a Fellow of the Royal Australasian College of Physicians (FRACP) in 1981. During his specialist clinical training he developed a keen interest in multiple sclerosis which he has continued since then. After completing his clinical training in neurology, he was a research scholar in the field of multiple sclerosis at the Institute of Neurology, Queen Square, London, and was awarded a PhD from the University of London and Queen Square Prize for Research in 1983. From 1984 to 1986 he continued this research as a Research Fellow at the John Curtin School of Medical Research, Australian National University, Canberra. In 1987 he was appointed Senior Lecturer in the Department of Medicine, The University of Queensland, at the Royal Brisbane Hospital. In 1989 he was awarded a Doctorate of Medicine from The University of Queensland for his research in the field of multiple sclerosis and was promoted to Reader in Medicine. In 1995 he was promoted to Professor of Medicine (Personal Chair), The University of Queensland, which he held until his retirement in 2021. His main clinical and research interest is multiple sclerosis. He also held the positions of: Consultant Neurologist, Royal Brisbane and Women's Hospital, 1987–2021; Director of Neurology, Royal Brisbane and Women's Hospital, 1992–2005: Director of the Neuroimmunology Research Centre, The University of Queensland, 1991–2007; Director of the Multiple Sclerosis Research Centre, The University of Queensland, 2009–2014; and Clinical Fellow, QIMR Berghofer Medical Research Institute, 2017–2021. In 1996, with the support of the Multiple Sclerosis Society of Queensland, he established a Multiple Sclerosis Clinic at the Royal Brisbane and Women's Hospital. In 2006 he was awarded the Multiple Sclerosis Australia Prize for Multiple Sclerosis Research - "For outstanding commitment and dedication to research into the cause and cure of Multiple Sclerosis in Australia". In 2011 he received the John H Tyrer Prize in Internal Medicine, The University of Queensland, for research in the field of Internal Medicine. He was the Sir Raphael Cilento Orator of the Royal Australasian College of Medical Administrators for 2009 and the W Ian McDonald Lecturer of the Australian and New Zealand Association of Neurologists for 2014. In 2019 he received the John Studdy Award from Multiple Sclerosis Australia for "lifelong commitment and service to research to identify the cause of and potential cure for Multiple Sclerosis". In 2024 he was appointed a Member of the Order of Australia for significant service to medicine, particularly neurology and multiple sclerosis research, and to tertiary education. Major research achievements include: the discovery of apoptosis of autoreactive T cells in the central nervous system as a fundamental mechanism of recovery from autoimmune attack (Journal of the Neurological Sciences 1991, Journal of Autoimmunity 1992, European Journal of Immunology 1994); formulation of a novel hypothesis (The Lancet 1998) proposing a failure of this mechanism in multiple sclerosis; and the further development of this hypothesis into a new paradigm (Trends in Immunology 2003) for the cause of human chronic autoimmune diseases based on infection of autoreactive B cells with the Epstein–Barr virus (EBV), some of the predictions of which have already been verified in multiple sclerosis, rheumatoid arthritis and Sjögren’s syndrome. His EBV hypothesis led to the first clinical trial of EBV-specific T cell therapy in multiple sclerosis (JCI Insight 2018), a trial in which he was a principal investigator.

Yang is currently a Honorary Research Fellow in UQ School of Public Health and a Research Fellow in Cancer Epidemiology Division of Cancer Council Victoria. He has extensive experience in analysing large-scale national and international health surveys and hospitalisaiton datasets with complex statistical models. He is interested in answering a couple of research questions in the population level (e.g. the associations between modifiable behaviors and chronic diseases; the inequalities in chronic disease risk).
I began my career working in industry for a company which specialised in in vitro diagnostic assays, for both human and veterinary health (AGEN Biomedical). There, I worked as a scientist for almost a decade in numerous departments of the commercialisation pipeline, including manufacturing, product development and research. Following this, I completed a PhD (2010) with the Australian Biosecurity Co-operative Research Centre for Emerging Infectious Disease and have since worked as a virologist at The University of Queensland.
My current research focuses on mosquito-borne virus discovery and the development of innovative vaccine and diagnostic platforms. Together, these research interests have culminated in a greater understanding of the mosquito virome and the development of new approaches for the detection of novel viruses. These include high throughput sequence and antigen-independent assays and the development of suites of unique monoclonal antibodies (mAbs), which in conjunction with deep sequencing platforms, provide comprehensive virus discovery strategies. Using this repertoire, I have been involved in the discovery and extensive genetic and phenotypic characterisation of new mosquito-borne viruses, belonging to more than six viral taxon (including Flaviviridae, Mesoniviridae, Bunyavirales, Reoviridae, Negevirus, Nodaviridae).
Harnessing the unique mosquito-specific growth restriction of the insect-specific flaviviruses that we discovered, my research now focuses on the application of these viruses to the development of novel, safe vaccines and diagnostics for multiple pathogenic flaviviruses.

Dr Juan Carlos Polanco leads a research team on "Extracellular Vesicles and Neurodegenerative Disorders" at the Clem Jones Centre for Ageing Dementia Research (CJCADR), part of the Queensland Brain Institute (QBI) at the University of Queensland (UQ). He holds an MSc in Biochemistry from the National University of Colombia and a PhD in Molecular Bioscience from UQ. During his PhD, Dr Polanco made significant contributions to understanding how SOX genes are involved in XX disorders of sex development. He furthered his expertise during a postdoctoral fellowship at CSIRO, developing assays to detect unstable human-induced pluripotent stem cells prone to tumorigenesis.
In 2013, Dr Polanco joined Prof. Jürgen Götz's lab at CJCADR, where he began pioneering work on small extracellular vesicles, known as exosomes. His highly cited 2016 paper in the Journal of Biological Chemistry was the first to demonstrate that exosomes encapsulate 'Tau seeds' capable of inducing Tau aggregation in recipient cells. He also showed that exosomes can propagate between interconnected neurons and that some exosomes internalised by neurons are re-released by hijacking endogenous secretory endosomes, thereby increasing their pathogenicity (Acta Neuropathologica Communications, 2018). Since 2019, Dr Polanco has secured NHMRC grants and leads a research team within Prof. Götz's larger laboratory at CJCADR.
