My area of research is within the field of cognitive neuropsychiatry, which applies the knowledge base of cognitive psychology to the study of psychiatric symptoms, such as delusional beliefs. My research has focussed on the role that cognitive biases (i.e., problematic thinking styles) play in the development and maintenance of delusions, both in individuals with schizophrenia and in those identified as "delusion-prone" (i.e., people with mild delusional beliefs or tendencies).
