The award's citation reads, "For seminal and field-defining contributions in the area of particle design and formulation, with particular emphasis on the science and engineering of wet granulation systems."

Litster's research on granulation and agglomeration is targeted at several levels:

• Particle level - Prediction of the behavior of partially saturated bulk powders and granules from understanding of the particle-particle and particle-binder interactions in the granule
• Rate process level - Mapping of regimes of operation for the key rate processes in granulation - wetting and nucleation, growth and consolidation, breakage and attrition and the development of mathematical models for these processes
• Unit operation and granulation circuit level - Development of scale-up rules for granulation processes. This includes simulation, optimization and control of continuous granulation circuits
