Overview

The human nervous system is no longer thought of has hard-wired, and is in fact capable of rapid change throughout life. This plasticity is important for learning, memory and recovery from brain injury. I am interested in using emerging brain stimulation and imaging techniques to "artificially" induce plasticity in the human brain, to ultimately improve the treatment outcomes for various neurological conditions, particularly stroke. These stimulation techniques include transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS).

I completed a BSc in 1994 and received a First Class Honours in Physiology in 1995 from the University of Adelaide. I then completed a Bachelor of Physiotherapy Degree at the University of South Australia. Returning to research in 2005, I undertook a PhD at the University of Adelaide, which I completed in 2009. My doctoral studies focussed on a new and exciting area of neuroscience – neuroplasticity. At the time of commencing my PhD, it was becoming clear that various non-invasive brain stimulation techniques (such as TMS) were able to temporarily reorganise the circuitry in the human brain in a similar way to what happens when we learn something new or store a memory. I was interested in trying to understand why some people responded to these stimulation paradigms, and others didn’t. What I discovered was that it an important driver of plasticity in humans was when the stimulation was delivered. In effect, the brain seemed to learn better at night time compared to the morning. This has important clinical implications, as it suggests that rehabilitation might be more effective at a certain time of day.

I was awarded a University of Queensland Postdoctoral Fellowship in 2010, and then a NH&MRC Postdoctoral Research Fellowship in 2011 to investigate more intensely how the brains of stroke patients rewire. I am using state-of-the-art stimulation and imaging techniques such as TMS, magnetic resonance imaging (MRI) and electroencephalography (EEG) to understand how the brain reorganises when it stores information, and how we can boost this process.

In 2016 I have commenced a Senior Lecturing position within the School of Health and Rehabilitation Sciences at UQ. I am currently setting up my own brain stimulation and imaging laboratory, and am conducting experiments investigating the link between brain oscillations, sleep, plasticity and ageing.

Research Interests

  • Understanding the factors that influence neuroplasticity induction in humans
    Neuroplasticity, a key mechanism responsible for learning, memory and recovery of brain function, can be induced experimentally with brain stimulation. Using transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), I am interested in understanding the neural factors that might predict how individuals respond to plasticity induction
  • Neural oscillations and plasticity
    Synchronous oscillations in brain activity are thought important in "binding" remote but functionally related brain regions. These oscillations also have a role in promoting the consolidation of plasticity. I am using brain stimulation to induce brain oscillations, and to determine whether these oscillations might promote more robust plasticity induction in human cortex.
  • Brain connectivity and brain stimulation
    Understanding how the brain responds to local changes in cortical excitability is critical in improving our understanding brain function. I am interested in combining brain imaging (fMRI and EEG) and brain stimulation (TMS and tDCS) to probe the neural response to local perturbations in brain activity.

Research Impacts

Understanding the neural correlates of plasticity, and how to boost these processes, promises to have profound economic and social impacts to our society. If we can harness the beneficial effects of plasticity, we might be able to improve stroke recovery, minimise the cognitive deficits in demential and Alzheimer's disease, and also understand how students should learn most effectively.
