Description of Research Program
My lab focuses on two main areas of research: cognitive neuropsychiatry and functional neuroimaging. The objective of my cognitive neuropsychiatry research is to identify the cognitive operations underlying the primary symptoms of psychosis and schizophrenia. This is being explored by way of originally designed cognitive paradigms for memory confidence, source monitoring, reasoning, and semantic association. The objectives of my functional neuroimaging research are to gain a functional and anatomical understanding of the cognitive systems involved in psychosis and schizophrenia, and to develop new multivariate methods for analyzing fMRI data, with applications to integrating information from fMRI, EEG and MEG. We provide two applications for download, free of charge. One is called metacognitive training (MCT), which is a group-based program that uses research-based examples to increase awareness of the cognitive biases that may underlie delusions, and training patients to counter these biases. The other is called fMRI-CPCA, which is a multivariate analysis method for imaging networks of brain activity.
