Dr Jack Griffiths is a Research Associate in the Imaging and Microscopy Team at the National Synchrotron Light Source II, applying machine learning and coherent X-ray methods to defect detection in microelectronics.
While a Research Associate in the X-ray Scattering group, Jack developed the Ultrafast Pair Distribution Function technique to leverage state of the art X-Ray Free Electron Laser facilities and track the evolution of material structure on picosecond timescales.
Jack gained his PhD from the Nanophotonics group at the University of Cambridge, studying single molecule light-matter interactions. This leveraged large datasets of inelastic light scattering from plasmonic nanostructures measured using automated experimentation.
