Professor Ian Tucker

Ian TuckerProfessor Tucker is interested in the formulation and delivery of bioactives for human and veterinary applications. This can be divided into two broad research areas: delivery systems for optimal delivery of bioactives (drugs) and the study of absorption processes in order to achieve optimal drug delivery to target organs/cells.

Current research on delivery systems is focused on sustained release polymer matrix tablets, specifically the mechanisms involved in the coalescence of polymer particles in tablets and how this leads to the properties of sustained release. The aim is to understand how the physico-chemical properties of the drug, excipients and polymer affect the formation of stable polymer matrices in order to design tablets with predictable and stable release profiles.

Other delivery systems of interest include nanosystems (bilosomes and polymeric nanoparticles decorated with cell penetrating peptides) and oil-based systems for intramuscular injection. He is also interested in absorption processes, how bioactives cross biological membranes, the role of transporters and their stereoselectivity, how bile salts affect membrane fluidity and transporter function, and the blood–brain barrier.
To do his research, Professor Tucker uses cell-based assays, thermal analytical methods, particle sizing (PCS, laser diffraction), electron microscopy, helium pycnometry, texture analysis, analytical methods (particularly HPLC), factorial-designed studies and statistical analysis and regression methods for modelling release data.
