TUSAIL is an Innovative Training Network funded by Horizon 2020, comprising 15 academic and industrial partners, led by the University of Edinburgh. TUSAIL stands for “Training in Upscaling particle Systems: Advancing Industry across Length-scales”. Over the course of four years, TUSAIL will train 15 early-career researchers (ESRs) through a combination of PhD research, scientific training and industrial secondments.  The reliable, validated simulation methodologies and tools developed in TUSAIL will be disseminated to industry, enabling quantitative predictions of large industrial processes which will be of value for design, operation and optimisation.
