Profile

I am a Professor at the University of Sheffield. My research interests are diverse within this constantly growing area, ranging from mechanisms of granulation to particle breakage and particle–wall interaction studies. My research centres mainly on understanding mechanisms in granule formation, use and break up. The overall aim is to apply a scientific understanding of the process at different length scales to improve the final granule quality, hence enabling new, novel industrial applications and improvements in mechanical granule properties.

I am the chairman of the Agglomeration Working Party of the European Federation of Chemical Engineering, and a committee member of the IChemE Particle Technology Subject Group.  In addition to research activities I serve as a consultant in granulation in the pharmaceutical, chemical, enzyme, and food industries.  My group is also proud to host the 7th International Granulation Workshop in 2015 in Sheffield
Research

Granulation

The modern granulation process I work with is used in many industries to manufacture a wide range of products such as detergent, fertilizer, pharmaceutical tablets etc, and is extremely rich in its intellectual challenges.

My research strategy is centered on improving granule product quality, by linking the early stage of the granulation process with new equipment design, and in developing on-line monitoring systems. This approach also covers the mechanical characterization/modeling of the granules at different stages of the granulation process. Since the interactions between particle and solid equipment walls influence the particulate process, experimental and theoretical work has been developed to give more detail about these interactions.
Breakage/Size Reduction

Research in this area focuses on methods both encouraging and avoiding particle breakage and highlighting the differences between static and dynamic failure mechanisms in many different types of processes and particles.
Smart sphere

I also lead more diverse projects, including the development of a "large" particle capable of sensing its own environment including temperature, pH and the aerodynamic forces.

This 2 cm diameter smart sphere has the capability to receive wireless commands and also store the data continuously in its internal memory. This has proved particularly useful for studying conditions within a washing machine.
Scaling

In addition, I am currently involved in a project looking at scaling within the oil industry and how methodologies can be developed to avoid this persistent and disruptive problem.
