John Spence is distinguished for his innovative world-leading contributions to both biology and materials science. He led the team which conceived the first application of X-ray free-electron lasers (XFEL) to structural biology using protein nanocrystals and he pioneered femtosecond serial crystallography. He is also a world leader in the development and application of atomic-resolution electron microscopy. For example, he co-invented a widely used technique for locating impurity atoms in nanocrystals and published the first observation of dislocation kinks, at atomic resolution. He has developed new microscopies and spectroscopies which have given scientists new eyes to understand atomic processes in solids.
