Bio
Dr. Edgar has more than 25 years of experience using non-invasive imaging – including 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.
As an example, over the last five years Dr. Edgar has been involved in the development and use of Artemis 123, a novel pediatric MEG system that provides optimal assessments of brain function in infants to children 3 years old. His most recent federally funded R01 research focuses on studying brain structure and function maturation processes in infants as well as young children. In addition to this research, Dr. Edgar is a licensed clinical psychologist in Pennsylvania.
Among his career achievements, Dr. Edgar was:
- Internationally recognized leader in clinical multimodal brain imaging research
- PI of two R01 studies examining brain development
- Co-developer of a pediatric MEG system, Artemis 123
- Developed digital signal processing courseware
- Statistician for the Children’s Hospital of Philadelphia Radiology Department
