My core research areas cover fine particle engineering, powder technology, aerosol and solid dose pharmaceutical drug delivery systems and related aerosol science, and employing this deep understanding into applications for industry product and process design, development and optimisation. The majority of my recent published research has had a focus on pioneering fine particle engineering for these dose forms, especially surface modification processes, via either mechanofusion, co-milling or spray drying with clear focus on practicality of scale up, adaptation to good manufacturing practice and commercial cost effectiveness. This work has included developing knowledge in specialist particle characterisation approaches, including powder rheometry, surface chemical speciation, surface energy measurement and cohesion measurement. Complementary to this, I have researched novel aspects of controlling powder blending, size enlargement and compaction behaviour.
