- Profile
-
I completed my undergraduate degrees in Chemical Engineering at the University of Cambidge in 2003 and then subsequently read for a PhD in Chemical Engineering, which was awarded in 2007. This work was entitled, “The Effects of Natural Convection on Low Temperature Combustion,” and was awarded the Danckwerts-Pergamon Prize for the best dissertation produced in the Department of Chemical Engineering in 2007.
After the completion of my PhD, I was appointed as the Hertha Ayrton Research Fellow in Chemical Engineering at Girton College, Cambridge from 2007 until 2012. In 2011, I was awarded the Hinshelwood Prize by the Combustion Institute. This prize is awarded in recognition of meritorious work by a young scientist of the British Section of the Combustion Institute.
I was appointed as a Lecturer in Chemical Engineering at the University of Surrey in 2012, and was promoted to Senior Lecturer in 2017. I joined the University of Sheffield as a Senior Lecturer in 2019.
- Research interests
-
My research interests are centred on developing new mathematical models of flowing systems with multiple interacting physical or chemical processes. This work can be can be broadly split into work in two general areas, namely process safety (incorporating combustion, explosion and the dispersion of reactive chemicals) and the energy-water nexus, focussing on the use of low-cost technologies for the production of potable or irrigation water in arid regions.
Key research interests:
- Combustion
- Explosion
- Dispersion of reactive chemicals
- Electrodialysis
- Solar ponds
