Research Interests
We use a variety of tools to investigate the relationship between the mind and brain. In association with The MIND Institute (http://www.themindinstitute.org) we employ structural and functional magnetic resonance imaging (fMRI), magnetoencephalography (MEG), event-related potentials (ERPs) and other methods to examine human brain structure and function. Using these tools, we are investigating the basic organizational principles of perception, learning, memory, attention and language in healthy individuals. We also use these methods to examine the neural basis of psychiatric disorders such as drug and gambling addiction, psychopathy and schizophrenia. We are also developing new methods of data analysis and combining data from different imaging techniques in order to gain fundamentally new information on human brain structure and function, and to expand the boundaries of brain imaging techniques.
