Professor Doddrell is distinguished for his developments of innovative and unique methods for applyiog NMR spectroscopy to structural organic chemistry, magnetic resonance imaging and image directed spectroscopy. With his co-workers he published the first analysis of gradient enhanced spectroscopy in terms of product-operator algebra He invented the elegant "DEPT" pulse sequence, in worldwide use for the past decade or so by structural chemists, and the SPACE pulse sequence. The latter allows the acquisition of signals from a known voxel, the signals having a very short relaxation time. His innovative method of correcting gradient induced Bo temporal shifts by phase modulation is being implemented by General Electric on all of their MRI equipment for high speed imaging.
