Dr Jin Sun is a lecturer at the School of Engineering in the University of Edinburgh. He obtained his PhD degree in mechanical and chemical engineering from Iowa State University in the US in 2007 and conducted his post-doctoral research in Chemical Engineering in Princeton University. His research aims to establish predictive links between particle properties and interactions and their collective behaviour in dense granular flows during diverse processes, such as fluidisation and silo discharge. To this end, he employs and develops computational and theoretical tools synthesising particle-scale experimental data, discrete element simulation, continuum and statistical mechanics in a multiscale modelling framework. Recently, he is focusing on understanding particle behaviour in additive manufacturing processes, advocating a greater appreciation of particle technology in this new area.
