Background
Andrew McBride became interested in computational modeling of discrete and granular systems during his MSc studies in Civil Engineering. After working as a civil engineer, he joined the CMR in 2002 as a research officer. The focus of the research was modeling comminution devices. Andrew was employed by the CMR part time during his PhD studies in extended models of crystal plasticity. After completing his PhD he undertook postdoctoral research in non-classical models of diffusion and nonlinear mechanics at the University of Erlangen-Nuremberg, Germany. He returned to South Africa in 2012 as a senior research officer in the Centre for Research in Computational and Applied Mechanics and the CMR. He currently heads research into breakage modeling.
