###### Hi there,

I am a current student in the Mathsys II CDT studying for a PhD in Mathematics of Real-World Systems. My research interests span mathematical models that involve hybrid and multi-scale dynamics, stochastic processes, numerical integration, epidemiology and fluids mechanics. To be honest, any topic that invokes the use of a mathematical model is of interest to me!

More specifically, my PhD project, supervised by Dr. Massimiliano Tamborrino, is focused on the development of time-parallel numerical integration algorithms using probabilistic methods. These algorithms have a wide range of applications for solving ODE and PDE problems in areas from climate modelling to space weather. Our focus application however is speeding up the simulation of nuclear magnetic fusion in collaboration with our external partners Dr. Debasmita Samaddar and Dr. Lynton Appel at UKAEA.

##### Research Projects

MSc Individual Project (2020) - Hats and pancakes in the sky: high-speed droplet dynamics

• A first incursion into the development of models to predict droplet deformation and trajectory in the face of an incoming aerofoil using high resolution direct numerical simulations (DNS) in Basilisk.
• Supervised by Dr. Radu Cimpeanu and Dr. Ed Brambley.

[Deformation of a half-droplet interface at successive times t = 250, 300 and 350 as the flow field accelerates from the right hand side. Simulations were calculated on an adaptive mesh solver in Basilisk. ]

MSc Research Group Project (2020) - Stochastic parareal: an application of probabilistic methods to time-parallelisation

MSc Individual Project (2019) - Spin-down in the absence of reflected waves

• Main aims were to reproduce the results from the Physics of Fluids paper Spin-up and spin-down in a half cone: a pathological situation or not? using much simpler analytical and computational techniques and to identify any markedly different/contradictory results.
• Supervised by Prof. Edward Johnson at University College London.

Summer Research Project (2017) - Hybrid methods for simulating reaction-diffusion systems

• Ten week internship researching and developing a novel hybrid 'blending' algorithm to combine stochastic simulation algorithms (SSAs) with deterministic partial differential equations (PDEs) in order to simulate reaction-diffusion processes more efficiently.
• Supervised by Dr. Christian Yates, University of Bath.

[Hybrid blending method where particles in a one dimensional domain $[0,L]$ are tracked in compartments in $\Omega_C$ and $I$ whilst simultaneously tracked at their exact positions in $I$ and $\Omega_B$.

##### Invited Talks and Conferences

UKAEA Physics Seminar (2020)
