Angus J. Wilkinson is a professor of materials science based at the Department of Materials, University of Oxford. He is a specialist in micromechanics, electron microscopy and crystal plasticity.^{[1] [2]} He assists in overseeing the MicroMechanics group while focusing on the fundamentals of material deformation. He developed the HR-EBSD^{[3] [4]} method for mapping stress and dislocation density^[5] at high spatial resolution used at the micron scale in mechanical testing ^{[6] [7]} and micro-cantilevers^[8] to extract data on mechanical properties that are relevant to materials engineering.
