research interests

My current research interests focus on the particulate materials and material surfaces and their role in product manufacture including both biological and non-biological materials. I have developed a number of novel and leading edge methods for determining a range of surface and bulk physicochemical properties of powders and particulate materials including mechanical, topographical, chromatographic and surface properties.

Recent studies have included studies of protein aggregation, protein crystallisation and freeze drying. The group has world leading expertise in gravimetric charactisation methods as well as inverse chromatographic methods, having pioneered many of these approaches. For example, the water sorption characterisation of many classes of materials, especially pharmaceuticals, biomataterials and biopharmaceutical is an area of significant interest. Current and new project areas include:
