Peters' research is motivated by the desire to generate new imaging methods to improve current diagnostic methods for cardiovascular disease, and improve effectiveness of therapies. She focuses on magnetic resonance imaging. Her group has developed technology for electrophysiologists who treat patients with electrical abnormalities in the heart. These MRI methods allow electrophysiologists to see tissue characteristics responsible for electrical changes. They have also developed new methods for rapid imaging, using underesampled radial MR acquisition strategies. Mosty important, is to develop MRI methods in close collaboration with cardiologists and radiologists to detect early disease and monitor therapy.
Peters is also committed to training a new generation of biomedical imaging scientists. She believes in providing an environment with excellent MRI resources, knowledge about state of the art methods, and important questions in collaboration with clinicians and scientists, to generate creative new solution in medical imaging.
