Our perception is influenced greatly by our expectations - what, where, and when we predict events in the world to occur. My research is focused on how we learn when in time to expect things to happen, and how this active inference about the future influences the way we process incoming sensory signals.

I use electrophysiology (EEG) and brain imaging (fMRI) techniques to investigate how we learn regularities in the timing of events, and how this affects perceptual processing. I'm interested in the neural processes that underlie conscious, deliberate expectations and automatic, unconscious predictions about when we expect perceptual events to occur.

Controlled and automatic expectations underlie how we prepare and guide behaviour, and constrains the interpretation of what occurs around us. This has implications for both healthy and pathological brain processes involved in functions such as understanding speech, learning, and movement.

I joined the Cunnington lab in 2011 as an Honours student in the field of psychology. From 2012 to 2014 I acted as the EEG facilities manager for the School of Psychology and Queensland Brain Institute. I started my PhD in Cognitive Neuroscience in 2013 at the Queensland Brain Institute and Science of Learning Research Centre, under the supervision of Associate Professor Ross Cunnington and Dr Marta Garrido.
