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.
