Henry Chapman

Henry Chapman is a director of the Center for Free-Electron Laser Science at the Deutsches Elektronen-Synchrotron and the University of Hamburg in Germany. He carried out his PhD in X-ray optics at The University of Melbourne, Australia, work for which he was awarded the Bragg Gold Medal from the Australian Institute of Physics. Henry develops methods in coherent X-ray imaging, which began at Stony Brook University in New York. Later, at Lawrence Livermore National Laboratory in California, he led a team to demonstrate the concept of "diffraction before destruction" where an intense X-ray free-electron laser pulse gives rise to a pristine diffraction pattern of an object before its destruction by that pulse. This solves a serious limitation in X-ray structure determination by increasing the tolerable dose for high-resolution imaging and crystallography by many thousands of times. He led a large international collaboration to extend this work to the atomic scale with the method of serial femtosecond X-ray crystallography, which promises to overcome current bottlenecks in protein structure determination. His current research is focused on developing this method and extending it to the smallest possible crystals: that is, single molecules. In 2015 he was a recipient of the Leibniz Prize from the DFG (German Research Foundation).
