I am an expert in the use of Large Eddy Simulation (LES) to study turbulent shear flows, and pollutant dispersion in urban environments. My urban pollution simulation work has been supported by the Royal Academy of Engineering/Leverhulme Trust, through a Research Fellowship. My main research interest is in the use of LES to create digital twins of urban environments, and combining simulation data with Virtual Reality in order to understand pedestrian and cyclist behaviour in polluted environments. I also have research interests in turbulent mixing layers, molecular mixing and reaction in shear flows, and the simulation of hydrogen and ammonia combustion for emissions reduction.
I obtained a Masters Degree in Physics with Astrophysics from the University of Leicester, and a PhD in Computational Fluid Dynamics from the Department of Engineering of the same institution. I held a Postdoctoral Research Associate position at the Rolls-Royce UTC, Loughborough University from 2007-2010, where I worked on the EPSRC Jet Noise project, and the CFMS SMURF project. Following a period as a Teaching Fellow in the Department of Engineering at the University of Leicester, I was appointed as a Lecturer in April 2013, and as Associate Professor in January 2022.
I am a Senior Member of the American Institute of Aeronautics and Astronautics, and I am a Fellow of the Higher Education Academy. I am currently Director of Research within the School of Engineering.

My research focuses on Large Eddy Simulation (LES). In particular:
- Simulations of urban pollution in real cities, and in idealised wind tunnel models. Modelling of the effects of vegetation on pollutant dispersion
- Combining LES with Virtual Reality to create digital twins, to understand human behaviour in polluted city streets
- Indoor ventilation simulation to understand pathogen dispersion, and fire propagation in buildings
- Simulations of turbulent mixing layers, with an emphasis on the effects of initial conditions of coherent structure evolution
- Simulations of mixing layers undergoing exothermic reactions (i.e. combustion)
- Hydrogen and ammonia combustion simulation for emissions reduction
- Inflow conditions modelling for Large Eddy Simulation
I am co-lead of the Turbulent Shear Flow Special Interest Group, as part of the UK Fluids Network.
PhD research projects are available in the following areas:
- Large Eddy Simulation of urban environment flows
- Digital twinning of cities for urban pollution mitigation
- Development of Virtual Reality models of contaminant dispersion in indoor and outdoor settings
- Numerical simulation of low-emissions hydrogen and ammonia combustion
- Growth and entrainment modelling of turbulent mixing layers
- Molecular mixing in turbulent shear flows
