Biographical details

I completed my PhD under Professor Mike Anderson in 2014 entitled "Intelligence and Task Structure Complexity: A Neurocognitive Investigation of Goal Neglect in Children and Adults". My PhD advisors were Murray Mayberry and Stephan Lewandowsky, and my PhD examiners were John Duncan, Lazar Stankov and Stuart Marcovitch. Both during and after my doctoral work I travelled to Switzerland, Spain and the UK to present at conferences and spend time at laboratories related to my research area, including the MRC Cognition and Brain Sciences Unit, Cambridge, UK, as a visiting scientist of Professor John Duncan. Returning to Perth I held a postodoctoral position at Murdoch University, where I set up the electrophysiology laboratory at Project KIDS (http://projectkids.com.au) - a long-running research program investigating the neurocognitive development of children. I also completed several experimental and methodological projects during this time focusing on the role of low-frequency oscillatory activity in complex goal-directed behaviour.

Research interests

  • Individual differences in cognitive control and fluid intelligence
  • Theoretical perspectives on human consciousness and intelligence
  • Methodological advances in electrophysiological data analysis
  • The role of oscillatory activity in complex goal-directed behaviour
  • Frontal lobe function across the lifespan

Teaching and supervision

I have taught and developed course materials for third-year undergraduate psychology statistics and research methods units at the University of Western Australia. I have also run programming and neuroimaging analysis workshops for postgraduates and academic researchers at both the University of Western Australia and Murdoch Univeristy.

I have supervised over 20 fourth-year research projects.

Past students of mine have investigated:

  • The interaction between task complexity, arousal and motivation in cognitive control paradigms
  • The relationship between low frequency oscillatory activity on the detection of sub-threshold stimuli
  • The neural mechanisms of task preparation and goal neglect
  • The effects of Type 1 Diabetes and Preterm birth on cognitive ability and electrophysiology in childhood and young adulthood

Current projects

I commenced work at the University of Sydney in September 2015 under Dr Micah Goldwater, Dr Evan Livesey and Professor Michael Jacobson.

Sixty percent of my time is spent in the School of Psychology and fourty percent is spent in the Centre for Computer Supported Learning and Cognition Centre (CoCo).

In both schools I am applying modern analytical and neuroscientific approaches to investigate the transfer of abstract knowledge to novel situations and how to best influence a participant's learning strategy.
