Stay tuned for details on our 4th annual Huddle Up for Autism, when CAR and the Philadelphia Eagles join together once again to bring families living with autism a day of fun, education, and awareness at Lincoln Financial Field.
I am the Vice Chair of Research in the Department of Radiology of the Children's Hospital of Philadelphia. I have a particular interest in how the brain of a person with autism processes sounds, words and pictures. I use MEG technology (magnetoencephalography) to "map" the brains of children with autism by measuring the brain's electrical activity in space and time. The cutting edge technology in the MEG scanner allows me to measure electromagnetic signals from the brain, providing new insight into the mechanisms of autism and other neurodevelopmental disorders.
Additionally, I am interested in ways to improve techniques and methods in neuroradiology that enhance scientists' ability to look at the brain.
I have been working in the field of medical imaging for over 20 years. I obtained my BA, MA and PhD from Cambridge University in 1988, 1991 and 1992. In addition to my position at Children’s Hospital, I presently hold the Oberkircher Family Chair in Pediatric Radiology and am Professor of Radiology at the University of Pennsylvania. Prior to these appointments, I undertook a post-doctoral fellowship in the field of diffusion and perfusion MRI in the Department of Radiology at University of California at San Francisco (UCSF) with Mike Moseley and John Kucharczyk. I was on the faculty at UCSF from 1994 to 2002, where I established the Biomagnetic Imaging Laboratory in 1993 and was Professor and Vice Chair of the Department of Medical Imaging at the University of Toronto before moving to CHOP. I am Vice-President of the American Society for Functional Neuroradiology and Secretary of the International Society for the Advancement of Clinical MEG.
