My research interests are in human visual perception, with a particular focus on face processing and adaptation. I use a combination of behavioural psychophysics and electroencephalography (EEG) to infer the neural mechanisms underlying face coding and determine how they are affected by our past experiences.
I completed my PhD in Psychology in 2015 at Macquarie University, Sydney, Australia, under the supervision of Dr. Kevin Brooks. From 2015 through 2017 I was employed as a Postdoctoral Scholar under the supervision of Drs. Michael Webster and Fang Jiang at the University of Nevada, Reno, USA. Since returning to Australia I have been working Postdoctoral Research Associate at Flinders University under the supervision of Dr. Michael Nicholls.
