Rate My Professor Rohan Walker

Professor Rohan Walker is a Professor in the School of Biomedical Sciences and Pharmacy at the University of Newcastle, Australia, within the College of Health, Medicine and Wellbeing. He earned his PhD in Neuroimmunology from the University of Newcastle in 2006. His distinguished career encompasses leadership roles such as Interim Pro Vice-Chancellor - Research, Deputy Head of School (Partnerships and Commercialization), Director of the Centre for Advanced Training Systems (established 2014), and Deputy Director of the Centre for Rehab Innovations. Earlier appointments include Peter Doherty Australian Biomedical Research Fellow (NHMRC, 2007–2010), NHMRC Early Career Fellow, Senior Research Fellow at the Hunter Medical Research Institute (2011), and Research Fellow at the University of Newcastle School of Biomedical Sciences and Pharmacy (2011–present).

Professor Walker's research focuses on neuroscience, psychoneuroimmunology, stress biology, neuroinflammation, microglial plasticity and function, neuron-glia interactions, stroke recovery and secondary neurodegeneration, cognitive performance under stress, depression, learning and memory, and objective measures of stress. He investigates the impacts of chronic stress on brain regions like the prefrontal cortex and develops biometric-enhanced training platforms, including virtual reality tools like Performance Edge VR for stress management and TACTICS VR for stroke care workflows. Notable publications include 'Chronic stress alters the density and morphology of microglia in a subset of stress-responsive brain regions' (Brain, Behavior, and Immunity, 2010), 'Evidence that microglia mediate the neurobiological effects of chronic psychological stress on the medial prefrontal cortex' (Cerebral Cortex, 2012), 'Development of a modular stress management platform (Performance Edge VR) and a pilot efficacy trial' (PLOS ONE, 2021), and 'Clopidogrel Administration Impairs Neurovascular Unit Recovery' (2024). He has led 68 grants totaling over $15 million, supervised 24 PhD and Masters students to completion, and collaborates with organizations including the Australian Defence Force, NSW Health, Defence Science and Technology Group, and Ramsay Healthcare. Awards include the Psychoneuroimmunology Research Society recognition (2005) and Newcastle Business Club's Young Business Person of the Year (2013).
