I am investigating outcome prediction in stroke. Specifically, I am exploring the efficacy of resting-state electroencephalography (EEG) in stroke prognosis across a range of cognitive, functional and psychological domains that are commonly affected by stroke and often associated with poor outcomes in stroke survivors. I will be comparing this data with accuracy of clinician prognosis to create a model that best predicts these outcomes up to 12 months post-stroke.

My research centres around the association between spatial attention and fatigue in the healthy brain. Specifically, I will be investigating the neural mechanisms that lead to a shift in spatial attention as a result of mental fatigue and under which conditions this shift is evident, through employing prolonged cognitive tasks and conducting sleep restriction studies. I will also use electroencephalography (EEG) to measure alpha band activity as an index of mental fatigue and eye tracking devices to measure the direction of eye movement.

I am interested in how our visual systems are influenced by what we have recently seen, and what we expect to see in the future. My research focuses on how repeated exposure to the same face or object can alter the response properties of neurons that encode these stimuli (known as stimulus-specific adaptation or repetition suppression). I am also investigating the automatic predictions that we make about our visual environment and how these predictions are expressed in electrophysiological recordings. I use a variety of techniques including event-related potentials, fast periodic visual stimulation and multivariate pattern classification.

I have a broad interest in cognitive ageing and factors that help people maintain their cognitive functioning in later life. In particular, I am investigating cognitive reserve in older people, and how this operates in the brain. I use various brain imaging techniques, including electroencephalography (EEG) and Magnetic Resonance Imaging (MRI).

I have a broad interest in how we change both cognitively and physiologically throughout ageing. My research investigates how we could decrease future dementia risk in older adults undergoing elective cardiovascular surgery. Specifically I will be using cognitive training regimes to attempt to minimise the cognitive deficits caused by post-operative delirium (occurring in up to 50% of patients), as delirium greatly increases future dementia risk.

Over 12,000 patients undergo cardiovascular surgery in Australia every year, with older patients increasingly undergoing these procedures. There is limited current evidence suggesting that these patients are more vulnerable to cognitive decline. My research investigates the short and long-term cognitive effects of cardiovascular surgeries in the older population, and what biomarkers (olfaction, gait speed, rate of eye-blinking and electroencephalogram/EEG power spectrum) predict response.

I am interested in the link between nutrition and successful cognitive ageing. My research focuses on the Mediterranean diet, and its potential to improve cardiovascular health, protect cognitive function and reduce risk of dementia. To assess changes in cardiometabolic and cognitive function following adherence to a Mediterranean diet I will be conducting three randomised clinical dietary intervention trials at the Sansom Institute for Health Research, collaborating with CAIN and the UniSA Alliance for Research in Exercise, Nutrition and Activity (ARENA).
