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.

Hormone receptor positive breast cancer and therapy resistance
Prof Elgene Lim is a medical oncologist at St Vincent’s Hospital and Head of the Connie Johnson Breast Cancer Research Lab at the Garvan Institute. Following his PhD at the Walter & Eliza Hall Institute where he identified the aberrant cells in carriers of the BRCA1 mutant gene, a hereditary breast cancer syndrome as the culprit cells giving rise to breast cancer, he furthered his research and clinical training at the Dana-Farber Cancer Institute and Harvard Medical School. He was awarded the National Breast Cancer Foundation Practitioner Fellowship in 2014 and returned from Boston to Australia. In 2017, he was awarded the inaugural National Breast Cancer Foundation Endowed Chair, and subsequently appointed the Principal Cancer Theme Lead at UNSW.
