RESEARCHER PROFILE
Filmed in Sydney, Australia | April 2026
Associate Professor Sudarshini Ramanathan is a neurologist and clinician scientist whose work focuses on autoimmune neurological disorders. Her research has helped identify new neurological syndromes due to antibody-mediated demyelination and encephalitis, and improve diagnostic tools and treatment guidelines for patients with autoimmune diseases affecting the brain, spinal cord, muscles and nerves.
Associate Professor Ramanathan’s research program aims to improve our understanding of underlying disease pathogenesis with a focus towards ‘precision medicine’ in neuroimmunology – both with diagnosis and therapeutics. Her research focuses on defining the clinical, radiological, and immunophenotypic profiles of specific pathogenic autoantibodies; understanding what triggers autoimmunity and disruption of immune tolerance; and the cellular and humoural mechanisms of action of autoantibodies and how this might be translated into refining novel therapeutic approaches.
Her work thus far has resulted in the enhanced recognition of novel treatable neurological conditions, important biological insights into the pathophysiology of these disorders, and the development of diagnostic criteria and therapeutic approaches to improve outcomes in vulnerable patients who otherwise risk chronic disability.
Associate Professor Ramanathan heads the Translational Neuroimmunology Group at the Faculty of Medicine and Health, University of Sydney; and also runs a neuroimmunology clinic at Concord Hospital. She supervises and mentors a research team of PhD and Masters candidates, postdoctoral fellows, and clinician researchers. Her research has been recognised by the Leonard Cox Award for Excellence in Neuroscience research and the NSW Premier’s Prize Award for Early Career Researchers (Biological Sciences) in 2022.

Genetics and Environmental Factors of Glaucoma & Myopia
Professor David Mackey’s original research, over more than 30 years into the genetics of glaucoma and in the fields of optic atrophy and congenital cataract, has received constant professional accolades, attracted ongoing research funding and led to his publication of more than 400 peer-reviewed papers.

Identification, characterisation and role of leader cells in ovarian cancer progression
Dr. Maree Bilandzic is a molecular cancer biologist dedicated to advancing the understanding and treatment of ovarian cancer (OC). Her research addresses critical gaps in OC treatment by investigating the mechanisms behind metastasis, chemotherapy resistance, and tumour recurrence. By utilising innovative methodologies and disease-representative models, Dr. Bilandzic has pioneered the identification and characterisation of leader cells (LCs)—a unique, stem-like subpopulation within tumours that plays a crucial role in OC progression.

Food and fasting periods as medicine to prevent disease
Professor Leonie Heilbronn is based at the South Australian Health and Medical Research Institute (SAHMRI), where she leads the Obesity and Metabolism laboratory. Her research is at the interface between basic and clinical science. She is internationally recognised for her work in nutritional modulation in humans and has made major contributions to our current understanding of mechanisms underlying conditions such as insulin resistance, particularly inflammation and lipid metabolism. She has also contributed significantly to current concepts of caloric restriction (CR), intermittent fasting (IF) and time restricted eating (TRE) in humans. She has published more than 110 peer reviewed papers in scientific journals and is an Associate Editor of Obesity, and Obesity Research and Clinical Practice.
