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.

Targeting chemotherapy resistance in ovarian cancer patients
Dr Alex Cole, from the Centenary Institute’s Centre for Biomedical AI, is now leading the research focused on developing a new treatment to counteract a protein called follistatin (FST), known for making ovarian cancer cells resistant to chemotherapy.
By employing cutting-edge molecular biology and directed evolution techniques, the project aims to create nanobodies—small, precise molecules—that can block FST. If successful, these nanobodies could enhance the effectiveness of chemotherapy and improve ovarian cancer treatment rates.

Paediatric haemorrhage and airway procedures
Dr Shane George is a paediatric critical care physician working in paediatric emergency medicine and paediatric intensive care at Gold Coast University Hospital. He is the clinical lead for children’s critical care research for Gold Coast Health, and is a Senior Lecturer at The University of Queensland and Griffith University.
Associate Professor George is also an active clinician researcher on topics that span both emergency medicine and PICU practice including safety in emergency intubation, sepsis, haemostatic resuscitation in children and respiratory support therapies.

Cellular interactions responsible for development, maintenance, and strength of the skeleton
Professor Sims directs the Bone Cell Biology and Disease Unit at St. Vincent’s Institute of Medical Research and is a Professorial Fellow at The University of Melbourne and Australian Catholic University.
She leads a team who studies the cellular interactions responsible for development, maintenance, and strength of the skeleton. She completed her PhD at the University of Adelaide, followed by postdoctoral work at the Garvan Institute in Sydney then at Yale School of Medicine, in New Haven, Connecticut, where she studied the role of the estrogen receptor in regulating bone structure.
