I am a clinical and academic neurologist specialising in Deep Brain Stimulation (DBS). After initial neurology training in Melbourne, I completed fellowships in movement disorders/DBS at Oxford and Queen Square. I then worked as consultant neurologist to the DBS service at Oxford and completed a PhD investigating the mechanisms of DBS in Parkinson’s disease. Since returning to Melbourne, I have worked closely with Neurosurgeon Kristian Bulluss, running a busy DBS practice which spans University of Melbourne affiliated public hospitals and private practice. My research is based at the Bionics Institute, aiming to optimise subthalamic nucleus DBS for Parkinson’s disease. This led to the important discovery of “Evoked Resonance Neural Activity” (ERNA), a new biomarker with potential to deliver automated DBS programming and to trigger feedback ‘adaptive’ control. This research has been made possible by 5 NHMRC project/development grants and generous support from the Bethlehem Griffiths Research Foundation, Brain foundation, Lions International and the Colonial Foundation.
