Dr. Barker is a research scientist who works to develop magnetic resonance imaging (MRI) and spectroscopy (MRS) techniques for evaluating diseases of the human central nervous system. He also conducts research studies to determine the utility of these new techniques, particularly in the understanding and diagnosis of neurological, psychiatric and oncological diseases. At the Kennedy Krieger Institute, Dr. Barker is actively involved in research studies currently being performed at the FM Kirby Center for Functional Brain Imaging.
Dr. Barker attended Oxford University in the United Kingdom, where he received a Bachelor's of Arts degree in chemistry and a Doctor of Philosophy degree in physical chemistry. He conducted his post-doctoral research in magnetic resonance imaging and spectroscopy at the California Institute of Technology. He has been a faculty member in the Department of Radiology at Johns Hopkins since 1989. He is currently a professor of radiology and oncology at Johns Hopkins, and a 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.
