Research interests

I undertake research into a wide range of problems that involve fluid mechanics. I have successfully supervised many PhD students - please get in touch if you are interested in doing a Phd!

Engineering Fluid Dynamics

My research interests are motivated by the desire to better understand the behaviour of fluids in order to make advances in practical engineering systems. My work involves collaborations with engineering industrial partners, as well as with colleagues from the Faculty of Engineering here at Sheffield. I am particularly interested in micro-bubble mediated flows - this refers to flows where the injection of a stream of small micro-bubbles significantly improves transfer rates. This has applications to a wide range of applications, including distillation and water purification.


Rheology is the field of scientific research that investigates "how a fluid flows". I am particularly interested in fluids that don't follow the standard rules of Newtonian fluids. Such fluids are called complex or non-Newtonian fluids. My work in this area has involved experiments, asymptotic analysis and CFD modelling.

Microfluidics for Biotechnology

My research focuses on the solution of inverse problems that arise in the sensing and control of lab-on-a-chip chemical analysis and chemical microreactor applications, and path-lab-on-a-chip biomedical analysis. The work involves modelling flow in microchannels and is carried out in collaboration with the Microfluidics Group from the Department of Chemical and Process Engineering at the University of Sheffield.


My work involves modelling of the stably stratified atmospheric boundary layer and the analysis of meteorological observations. The Earth's boundary layer supports varied and complex waveforms, from internal gravity waves to turbulent eddies. I am particularly interested in large amplitude, solitary waves. In recent years this work has involved collaborations with the British Antarctic Survey, Meteorological Office and the Complutense University of Madrid.

Teaching interests

I have taught a wide-range of Maths modules, both for specialist Mathematics Undergraduates and for Engineering Undergraduates. I have an MEd in Teaching and Learning for University Lecturers, awarded by the University of Sheffield.
