I have been employed at the Welsh School of Pharmacy since 1990 as co-manager (with the late Dr Michael I. Barnett) of the Fresenius Kabi stability assessment and research laboratory, and as a teaching expert in the field of sterile product formulation and manufacture in the undergraduate degree course.

Investigating the various aspects of physical and physico-chemical stability of parenteral nutrition admixtures The application and comparison of particle size analysis equipment Design and validation of methods and equipment for manufacturing sterile dosage forms and devices. Particulate contamination of intravenous devices and delivery systems. Effectiveness and safety of intravenous lipid emulsions as drug delivery systems. Examination of the effectiveness of intravenous filtration devices.
