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.
