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 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.

Apathy is a commonly reported symptom in older adults residing in aged care and may be associated with an increased risk of cognitive decline. Reminiscence therapy, a powerful way of providing a connection with a person’s past, has demonstrated results in improving mood symptoms and quality of life. My research will focus on reducing levels of apathy, combining both reminiscence therapy and immersive virtual reality.

I am a clinician, interested in exploring the relationships between depression and dementia, particularly their neuropsychological profiles.  I have just started and am currently writing my proposal.

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 (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).
