Personal profile
Biography
I am an applied mathematician and engineer by training and am interested in determining the fundamental physics of industrially relevant fluid mechanics problems. My research incorporates a combination of advanced asymptotic and numerical modelling techniques.
I completed both my undergraduate (Mathematical Engineering - 2012) and postgraduate (Applied Mathematics - 2015) degrees at the University of Birmingham. My doctoral thesis concerned the stability of three-dimensional non-Newtonian boundary layer flows. Since completing my PhD I have held lectureships at the University of Leicester, Oxford Brookes University and Coventry University. In addition to this, I often visit the University of Sydney and Université Grenoble Alpes to undertake collaborative research work.
I joined Aston University in September of 2022 as a Senior Lecturer in Applied Mathematics. In 2025 I was promoted to Reader. I have experience teaching across both Mathematics and Engineering undergraduate degree programmes and am a Senior Fellow of the Higher Education Academy (SFHEA).
I currently hold an EPSRC Mathematical Sciences Small Grant and was previously awarded an EPSRC New Investigator Award. As part of these projects, I supervised two excellent post-doctoral students - Dr Liam Escott and Dr Dongdong Xu. I have supervised and co-supervised numerous doctoral students and continue to supervise bachelors- and masters-level mathematics and engineering projects in Fluid Mechanics.
I am part of the UK Fluids Network (UKFN) and contribute to two Special Interest Groups (SIGs): Non-Newtonian fluid mechanics and Boundary layers and complex rotating flows.
I am always happy to hear from prospective students. If you would like to come and work with me, feel free to get in touch via email so that we can discuss potential projects.
