- Internal Dynamics of Impacting and Coalescing Reactive Droplets
I graduated from the University of Leeds in 2016, with a BSc degree in Mathematics. During my undergraduate degree, I particularly enjoyed the three modules in fluid dynamics I studied, and applied mathematics in general. Throughout, I aimed to give myself a well-rounded education in mathematics by studying modules spanning all areas of the subject, including statistics and pure mathematics.
In the summer of 2015, I undertook a research project entitled 'Anonymisation of Healthcare Records' at the University of Leeds. During the project, I was based in an inter-disciplinary research centre, the Leeds Institute for Data Analytics (LIDA), alongside a diverse range of researchers. This experience demonstrated the importance of the multidisciplinary approach to me, and made me keen to pursue postgraduate research. For my final year project, I studied Monte Carlo Methods, which are a set computational methods which use repeated random sampling to evaluate numerical results.
I am primarily interested in droplet dynamics, especially involving a solid surface (wetting). In my PhD project, I am investigating the internal dynamics of coalescing droplets, both numerically (using the C++ toolbox OpenFOAM) and experimentally (using high speed imaging). Such flows have numerous applications, from microfluids (e.g. lab-on-a-chip devices) to sprays, but I am especially interested in next-generation additive manufacturing techniques (e.g. reactive inkjet printing) where mixing between coalescing droplets is a primary concern.
I am also interested in complex fluids; in particular, colloidal suspensions. In my MSc team project (working with Procter & Gamble), I investigated the influence of centrufugal force on the sedimentation of colloidal suspensions and developed an improved model for these flows. The model results were succesfully validated against highly controlled experiments, with the work published in Physics of Fluids.
I have previously worked on statistical methods for linking anonymised data records, and Monte Carlo Methods in statistical physics.

Why I chose the CDT in Fluid Dynamics
My main reason for choosing the CDT was the multidisciplinary environment it provides. I was also attracted by the cohort based nature of the CDT, with a community of fluid dynamics postgraduate researchers studying various strands of the subject. This allows me to better appreciate areas of the fluid dynamics not directly related to my own research are
