Research summary

My current interests concern 21st Century Fluid Dynamical Challenges in Water Purification. My specific research involves the development of mathematical models for water purification strategies, including heavy-metal removal via magnetic separation, membrane filtration, and adsorption and ion-exchange techniques. In each area I use a blend of analytical techniques, including asymptotic analysis and numerical modelling, to gain insight into the physical behaviour of the system. The resulting models are then used to predict whether a particular system offers a viable route to generating pure water, and if so how such a system should be operated to maximize productivity.

I work in collaboration with two experimental research groups: the Complex Fluids Group in Princeton University, and the Laboratory of Fields, Flows, and Interfaces, in Ryerson University. I also work in partnership with Pall Corporation, the world-leading membrane and separation science industry. Close collaboration ensures that the mathematical models that I develop are directly applicable to the real-world challenges.

Filtration and separation technology also spans a range of other applications, including biotechnology, the pharmaceutical industry, transfusion medicine, energy, electronics, and aerospace, and I am interested in the exploration of such technological advances that share common modelling features.

In the wider context of fluid mechanics I have an active interest in the mathematical modelling of glass tube and sheet manufacture, in collaboration with glass industry Schott AG, and in polymeric nanofibre manufacture.
