Personal profile

Biography

I am a neurologist and cognitive neuroscientist currently based at the Monash Institute of Cognitive and Clinical Neurosciences in Melbourne, Australia.

I completed both my undergraduate research training (BMedSc) and medical training (MB,BS) with Honours at Monash University in 2002. I then embarked on my doctoral research with Jason MattingleyRoss Cunnington and Mark Williams at the University of Melbourne, and in collaboration withNancy Kanwisher at MIT. After being awarded my PhD in 2007, I returned to speciality training in Neurology via St. Vincent's Hospital and The Alfred Hospital in Melbourne, and was admitted to Fellowship of the Royal Australasian College of Physicians (FRACP) as a consultant neurologist in 2013. That year, I was awarded an NH&MRC Neil Hamilton Fairley Early Career Fellowship, which I took to Oxford to work with Masud Husain. I returned to Australia in 2015 to the ARC Centre of Excellence for Cognition and its Disorders in Sydney, before commencing my current position as Senior Research Fellow at Monash University.

 

Research Interests

My research addresses some of the fundamental issues in cognitive neuroscience with the aim of achieving a deeper understanding of the mechanisms underlying behavioural deficits in the diseased brain. The themes of my research are:

  1. Decision-making: When we decide to perform an action, we often need to balance the benefit of performing that action with the costs associated with it. My recent research centres on the mechanisms underlying these computations in healthy individuals, as well as patient populations who may have disorders of decision-making (e.g., Parkinson's disease).

  2. Attention, Consciousness and Memory: How does the brain generate a conscious experience of the world and our place within it? Much of my research has centred on the mechanisms of attention. More recently, I have been interested in the role of conscious and non-conscious mechanisms in recognition memory, in both healthy populations and those with focal lesions of the medial temporal lobe. 

I use a combination of approaches, including:

  • Classical behavioural psychophysics

  • Structural and functional brain imaging

  • Lesion/Patient studies

I am always interested to hear from motivated undergraduate and postgraduate students.
