Research

P4G

My main research interests lie in the processing of stiff pastes, and the densification of particulate material via compaction. My work has focused on the effect of paste preparation and extrusion-spheronisation processing conditions on the mechanism of pellet formation for water-based microcrystalline cellulose (MCC) pastes. Current work includes the compaction of granular biomass.
