Dr. Twieg has served on the Biomedical Engineering faculty since December 1990, and has worked as a Radiology faculty member at University of Texas Health Science Center at Dallas and as a Staff Scientist for Philips Medical Systems in the UC San Francisco/ VA Magnetic Resonance Spectroscopy Laboratory. He has published over 90 technical articles and abstracts.
Dr. Twieg's research interests include development of novel MRI acquisition techniques and image reconstruction algorithms, functional brain MRI techniques, and application of high-field functional MRI to studies of visual processing, oculomotor function, stroke recovery, and other aspects of brain function.
