I also have a profile at the ARC Centre for Excellence in Cognition and its Disorders.


I received my Masterís of Science degree in Psychological Science from Montana State University where my work investigated the behavioural effects of neurodegenerative disease in animal models. Following a couple years working in industry I moved to Australia to commence my PhD at the ARC Centre of Excellence in Cognition and its Disorders. As part of the Memory strand at the CCD I investigate how individual differences in cognitive abilities modulate collaborative group memory. Specifically, I examine how attentional control and working memory influence the disruption present in collaborative recall and how these attributes affect subsequent memory following collaboration. Iím also involved in work with the Belief Formation group investigating social cognition and belief reasoning in schizophrenia and schizoaffective disorders.
