 to produce a mathematical framework for MRI coil design which was crucial to the development of ultra-fast echoplanar imaging (EPI).,, This technique allows the recording of changes in blood flow in the brain associated with brain function and was crucial to the development of fMRI.

From 1988 until 1993 he worked as a researcher at the National Institutes of Health

 in Bethesda, MD. Working with Denis le Bihan, a French neuroradiologist, he initially showed that EPI could be used to provide high quality maps of water diffusion in brain tissue, a discovery (known as Diffusion MRI

) which has led to the widespread clinical use of MRI in stroke, where water diffusion in the affected brain tissue drops very rapidly after the ischemic event. The technique also lies at the heart of diffusion tensor imaging, a method for non-invasive study of connecting pathways within the brain’s white matter.

In 1991, still at NIH, he was the first to show that EPI could be used to monitor the time course of oxygenation changes in animal brain resulting from changes in the breathing gas.,. This led to the discovery, made in collaboration with noted researcher Kenneth Kwong

 et al. appeared, showing similar results demonstrating that BOLD contrast enables the mapping of activation patterns in the working human brain. These findings led to an explosion of interest in fMRI, which depends almost entirely on the use of EPI to investigate human brain function, and the subsequent development of what has come to be known as Imaging Neuroscience.

In 1993 he returned to the United Kingdom as a Wellcome Principal Research Fellow to become head of MRI at the Wellcome Trust Centre for Neuroimaging

Since 2006, he has been director of the Department of Neurophysics at the Max Planck Institute for Human Cognitive and Brain Sciences, Leipzig. His work there centres on the quest to gain more precise knowledge of the structure and function of the human brain, by using more powerful MRI scanners and improved hardware and methodology.
