Professor, Departments of Radiology & Oncology; Research Scientist at the Kennedy Krieger Institute
Dr. Barker's current research interests include developing methods to non-invasively map out neurochemical and neurotransmitter levels in the brain in patients with brain tumors, infectious diseases, neurometabolic diseases, neurodegenerative diseases, schizophrenia and other psychiatric diseases using MRS. He is also interested in MRI techniques that can be used to non-invasively measure blood flow in the brain. A particular focus at present is to develop human MRI and MRS techniques for use at very high magnetic field strengths (7 Tesla). Dr. Barker collaborates on various MRI/MRS research projects with neurologists, neurosurgeons, oncologists and psychiatrists at Johns Hopkins and the Kennedy Krieger Institute.
