Dr. J. Christopher Edgar

Principal Investigator
Associate Professor of Radiology

Dr. Edgar has over 20 years of experience using non-invasive imaging (electroencephalography (EEG), magnetoencephalography (MEG), and structural and functional MRI) to study brain function and structure in psychiatric and neurological patient populations. He is also interested in conducting the basic research needed to assess the strengths and weaknesses of neuroimaging techniques, as well as inform the development of more sophisticated analysis techniques. Over the last 5 years his research has focused on using multimodal imaging to examine the maturation of brain function and structure in adults with schizophrenia and also children with autism.
